One of the most important parameters of this series of air handling units with heat recovery is its high energy efficiency due to the transfer of heat energy from the removed warm air supply cold.

The efficiency of modern membrane heat exchangers used in these units reaches 70%.

The use of Electrolux EPVS-1100 air handling units with heat recovery is especially important for our climate, when winter period year lasts 7-8 months a year.

According to the experience of our research and calculations, the payback period for air handling units with recuperation, on average, is 1.5-2 years of operation. When compared with equipment that heats the supply air with electricity.

High recovery efficiency is achieved by modern technology use of a membrane-type heat exchanger-recuperator with the possibility of transferring part of the heat with moisture through the surface of the recuperator.

However, recuperation alone is not enough for full heating, so it is necessary to install an auxiliary heater, although its power is already much less than what would be needed to heat the same volume of air without using recuperation.

Control

This model of equipment is completely controlled in a simple way. Switching on / off and regulation of the necessary parameters is carried out using the control panel:

They allow you to increase the performance of the installation at high pressure losses.

The characteristic shows how the performance changes with the use of retaining fans and without their use.

More detailed information about Electrolux EPVS-1100 units is presented by the manufacturer in the installation and operating instructions.

Maintenance and care:

For standard operating conditions (no serious air pollution environment and normal indoor climate) it is recommended to clean or replace the filters at least once every 12 months. It is advisable to carry out these procedures 1 time in 3-4 months.

Basic Description

The supply and exhaust units presented in our catalog are designed for supplying, as well as cleaning and removing exhaust air to rooms with a small area. This equipment allows you to heat and humidify the air without additional energy consumption due to the plate-type membrane type heat exchanger. Installation of air handling units is allowed both in the manned room and behind the false ceiling.

Standard equipment includes supply and exhaust fans, filters, plate heat exchanger, automatic control system with remote control remote control(PDU).

The fans are equipped with high efficiency impellers with backward curved blades, asynchronous electric motors, built-in thermal protection using thermal contacts with automatic restart. Sealed ball bearings provide long term air handling unit of this type.

The Swedish brand Electrolux (Electrolux) produces not only vacuum cleaners, washing machines and other household appliances. Among the products there are air conditioning equipment, including - and ventilation installations: forced-air and exhaust and forced-air.

Since the installation of such devices is only possible for specialists, we will not describe it in detail. Let's focus on an overview of the characteristics, features and benefits.

General description: about types of installations

ventilation units Electrolux are divided into 2 types:

1. Star EPVS: supply and exhaust, with recuperation and an electric heater. The line includes 6 models of different performance, the device and functions are the same.
2. Fresh Air EPFA: supply, with electric heater. The line includes 3 models of different performance, the device and functions are the same.

We will focus in the review mainly on the first line - it is more popular and widespread.

At structure of models Electrolux Star EPVS

The body of the units is rectangular, made of galvanized sheet steel. Inside - heat and sound insulation made of expanded polystyrene and foamed rubber.

In the body are located:

• 2 fans (one for supply, the other for exhaust), with overheating protection and 2 speeds;
• 2 temperature sensors, one directly at the inlet outdoor air, the second - at the outlet of the inflow from the installation (after the heater and the recuperator, that is, you can know exactly how many degrees it heats up);
• 2 filters, on the supply and exhaust, type EU-5 (not only to prevent polluted air from entering the room, but also not to pollute the heat exchanger);
• plate heat exchanger.

From two opposite sides of the body, two round pipes protrude, to which the air duct lines are connected. Fresh air from the street (inflow) flows along one line, air is drawn from the premises (exhaust) along the other. Inside, these lines cross, passing through the heat exchanger and "exchanging" heat.

Mounting brackets are located on the sides of the case: 2 pieces each (4 in total). On the one hand, there is a service hatch: through it you can remove the filter and the heat exchanger for cleaning.

Additionally, 1 more fan can be installed in the supply and / or exhaust line, EPVS-EF models - to increase the pressure. This will partially increase the amount of passing air. For each EPVS model, a separate corresponding fan model is designed (characteristics are given below).

For control, the devices have a wall-mounted control panel with a screen. You can read more about the remote control below.

Purpose and scope

Any model from the EPVS range can be used in ventilation systems residential and non-residential buildings(used for all areas of the building). It could be:

• private house;
• shop;
• office;
• public institution (cafe, restaurant, bar, and so on);
• swimming pool, gym;
• production room.

About industrial premises- there is a limitation. Installations are not designed to remove explosive impurities, acid vapor, varnishes, as well as for "heavy" suspensions.

Pros-cons

The advantages of the EPVS line include:

• separate places for air intake and exhaust;
• "hidden" installation;
• the ability to use with a duct system;
• the ability to install an electric heater (sold separately);
• the presence of a filter (and it can be cleaned);
• the presence of a timer with the ability to set several modes for different days / times;
• the presence of a remote control, which displays various readings.

The relatively high price is not a minus: the recuperators of this series are more serious devices than "ordinary" ones. household models(like UVRK or "Prana").

A small drawback is the lack of a remote control and an electric heater as standard.

Control method: wall remote

The unit is controlled from a wall-mounted plastic remote control (model - ERC-16), which is connected to the device via a cable. The remote control has a screen and 6 round mechanical buttons.

The screen is large, liquid crystal, with blue backlight. During operation, the following data is displayed:

1. Day of the week.
2. Current time.
3. Selected fan speed.
4. Supply air temperature (after the heat exchanger).

Also, the remote control can show the temperature at the inlet to the installation and the condition of the filter (signal that it is time to clean / change it).

Button assignment:

1. Turn on/off the remote control and settings.
2. Resetting the counter before cleaning / replacing the filter, viewing the air temperature at the unit inlet.
3. Set date/time, or enter timer setting mode.
4. Switching fan speed.
5. Decreasing the selected parameter by 1 unit, changing modes (when setting the timer).
6. Increase the selected parameter by 1 unit, change modes (when setting the timer).

Characteristics and prices of the Star EPVS line (air handling units)

In the line of air handling units with a heat exchanger includes 6 models. They are marked with numbers (name of the EPVS range + number) that indicate the approximate maximum air flow.

Additional fans are labeled as EPVS-EF + the number of the respective unit model (example: EPVS-EF 200).

List of models and approximate price for each unit and an additional fan for it:

1. EPVS 200: about 36,000 rubles(additional fan - about 5,000 more rubles).
2. EPVS 350: about 52,000 (6,500) .
3. EPVS 450: about 61,000 (7,500) .

Here are the main characteristics of the installations Electrolux EPVS, as well as additional fans ( EPVS-EF, sold separately):

Characteristics and prices of the Fresh Air EPFA line (air handling units)

In terms of device, Fresh Air EPFA air handling units differ from the EPVS line. First of all - they have only 1 line for air, supply. An electric heater is included as standard.

Models in the line of inflows are as follows:

1. EPFA 480.
2. EPFA 700.
3. EPFA 1200.

Each model available in several variations, the differences are in the power of the heater.

The characteristics of EPFA inflows are as follows:

Mounting Features

Devices of both lines are usually mounted horizontally, in the subceiling space. Mounting is carried out using self-tapping screws: the body is attached to the surface on 4 mounting brackets. Vertical mounting (on the wall) is also possible, but practically not used.

Air duct lines are laid from the installed device, through which air will be removed from the room (or rooms) and enter it.

During installation, access to the service hatch should be provided.

The STAR air handling unit is a compact recuperative device designed to supply, clean and remove exhaust air in small spaces. Heating and humidification of air is carried out without additional costs electricity. This happens due to a plate-type membrane-type heat exchanger, which extracts heat and moisture from the utilized air and transfers them to the incoming air from the street. Installation of the unit can be carried out directly in the served room and suspended ceiling.

Design

Standard units are equipped with supply and exhaust fans, supply and exhaust filters, a plate heat exchanger and an automatic control system with a remote control. The innovative type of heat exchanger allows to heat and humidify the supply air, while the special membrane of the heat exchanger transfers only water molecules from the exhaust air, leaving all impurities in it.
The fans of the units are equipped with high efficiency impellers with forward curved blades and asynchronous motors. Sealed ball bearings in motors are maintenance-free and provide extended service life. Fan motors are protected by built-in thermal contacts with automatic restart at 125°C.
The unit has two fan speeds, the ability to control an external electric heater (supplied separately) and electronic heat exchanger frost protection.
If there is an extended network of air ducts, additional fans of the back-up air (supplied separately) are installed sequentially in the supply and (or) exhaust air ducts.
The unit is designed for mounting directly to round air ducts.

Mounting

The air handling unit is delivered ready for connection. The unit is mounted horizontally in the subceiling space. During installation, it is necessary to provide access for after-sales service installations.

Not allowed:

Use for transporting air containing "heavy" dust, flour, etc.
to mount in explosive, fire hazardous rooms and for transporting air containing vapors of flammable substances.

Care

Clean the filter regularly depending on how dirty it is, especially in May-June, at the time of flowering. During this period, it may be necessary to clean the filter 2 or more times a month.
Do not use solvents or metal brushes to clean the filters and heat exchanger. Use a soft brush to remove dust.

Buy household appliances - half the battle. It is important to know how to properly install. If you want to save on the services of a master, we will tell you how the Electrolux dishwasher is installed. You will learn the details of doing the work with your own hands, which you will not find in the instructions.

First, decide on the size of the dishwasher. If you have a small family, then feel free to choose a compact version for 6-8 sets of dishes. When integrating the Electrolux PMM into a ready-made headset, it is important to choose the right place:

1. Compact model. Fits perfectly under the sink, just needs to be installed special siphon. Proximity to communications is a big plus. Also, the machine can be placed on the countertop, because its dimensions are no larger than a microwave oven.
2. Built-in narrow PMM. Fits in one of the cabinets kitchen set. It is advisable to choose a place to the right or left of the sink. If you buy equipment and order new kitchen, then a dishwasher cabinet is provided in advance.
3. Free standing model. Set up in a convenient location. You can push the cabinets and install the equipment or put it in a free corner.

It is important to place the Electrolux brand dishwasher evenly. The slope to one side should not exceed two degrees.

You can independently remake the wardrobe in the headset. To do this, remove the door from the hinges, remove all shelves and the back panel. Or make holes for the hoses in the side wall.

How to avoid voiding your warranty

Read the instructions carefully before installing the machine yourself. Each manufacturer specifies allowable norms when connecting equipment. Most dishwashers should not be connected to hot water. This leads to damage to hoses and filters.

If the PMM breaks down due to connection to a hot water supply, then you can not count on warranty repairs.

Another dangerous point is the connection to the mains. It is forbidden to connect powerful equipment to ordinary old sockets without a voltage stabilizer, as well as to plug it into one socket with an electric stove.

Wiring

If your network is not prepared, call a specialist, you should not deal with electricity on your own. What work is to be done:

1. Wall shattering. A puncher prepares a groove where a three-core copper wire is laid.
2. Euro socket installation. Since the PMM cord is rather short, it is recommended to place the outlet at a level of 45 cm from the floor. It must be waterproof and grounded.
3. Connecting a 16A difavtomat. It ensures the stable operation of the equipment.

Connecting and placing the dishwasher

Before starting work, prepare the components:

• Siphon with two or three drains. Additional fittings are useful for connecting other devices. As unnecessary, one fitting can be closed with a plug.
• Tee made of brass, bronze or metal-plastic. Thread ¾ inch. If the tee does not have a stopcock, then buy one separately.
• Filter. Installed to purify water from impurities.
• Hoses of the required length, if the standard ones are not enough.
• Fumka. Fum-tape of high-quality waterproofs the joints.

Of the tools you need an adjustable wrench, pliers, a screwdriver.

act in correct sequence. First you need to connect the drain, then the water supply and power supply. Judge for yourself what is more convenient for you: immediately connect all the outlets and install the dishwasher in the cabinet, or place it in place, and then start connecting.

Drain work

Fasten drain hose at the outlet of the siphon. At the top, it should bend so that runoff water does not enter the PMM hopper. The bottom bend (which comes from the machine) should be short and deep.

Water connection

Have you already decided which water supply to connect to? About hot water connection read our article. First of all, close the shut-off valve. Remove from water outlet kitchen faucet and old insulation. Install brass tee. Connect a mixer, a coarse filter, a dishwasher hose to the outlets (it is possible through a connecting tube - a hank). All connections are carefully insulated with a fum-let (wrap at least 10 times along the thread).

Additionally, install a ball valve if it is not on the tee.

It remains to plug the plug into the outlet. Now you can test run and check dishwasher In action. Open the stopcock and make a test run of the PMM without dishes. See that there are no leaks anywhere.

It is not difficult to connect the Electrolux dishwasher with your own hands. The main thing is to act consistently and follow the instructions. Video on the topic will help you:
