Air conditioning without external unit: device, principle of operation, installation
Monoblock air conditioners differ from all other variants of similar equipment in that they are a single case without additional external components. Whenever possible, such equipment can be classified into fixed and mobile installations. The first are attached to the wall or on the window opening. They feed on the outside air, which is provided by a pair of tubes.
Mobile air conditioners can work anywhere in the room and have a movable base with wheels. The only restriction on the location is the need to remove hot air outside the room. This is done with the help of a corrugated pipe, the length of which does not exceed 2 m. In connection with this, a mobile device is placed near a door, a window or near a wall.
The air conditioner without an external unit, like any other technology, has its drawbacks.They are expressed in the fact that the models located in the window opening reduce the intensity of the room lighting. It does not apply to the wall version. For most mobile products are characterized by:
- overdrying of air;
- high noise;
- not the most compact size.
In addition, they occupy additional space on the floor.
The consumer should be familiar with the types of air conditioners for an apartment without an external unit. Among others, floor and wall models should be distinguished, which differ in location. On sale there are also floor systems without duct.
The principle of their work is the forced evaporation of water. Heat energy is absorbed from the air. As a coolant in such floor air conditioners, water is used, which is supplied to moisten the porous filter. Condensed air is forced through it.
Before visiting the store, you should read reviews about air conditioners without an external unit. Consumer opinions about them are usually positive. This is due to the fact that the device is mobile and can work at any temperature of external air, which cannot be said about split-systems.
Consumers like not having to do a monoblock installation.It will only be necessary to remove the corrugation to remove heat from the room to the outside. But buyers do not like some of the features of such air conditioners. They consist in the increased noise level during the work, and also need of removal of condensate.
Mobile and stationary monoblock type systems look different, but they function according to a similar principle. Inside the case there are the following nodes:
- refrigerating machine;
- cleaning filters;
- Control block;
- drain pan.
An air conditioner without an external unit has three key nodes that are combined in a chiller. Among them should be highlighted:
- heat exchange circuit;
The drain pan can be replaced by a pump. The control unit is necessary for control. In order to better understand the design features of the described equipment, it can be represented by a conventional refrigerator, only operating on the scale of one room. Cold air enters the room, which is obtained by heat exchange in the evaporator circuit. In this case, the by-product is heat, which is released through the condenser circuit and is discharged outside.
The difference between stationary and mobile options is where the air comes from, it can be a street or a room. To date, on sale you can find air conditioners without an external unit, which work not only for cooling, but also for heating. This suggests that in one mode, the device operates on the principle of a fan heater. Modern devices usually include ceramic heaters.
Monoblock products have an electronic component, which provides for the presence of:
- digital control and management;
- multi-speed fans;
- automatic maintenance of the set temperature;
- adjustment, responsible for the direction of air flow blinds.
All this allows you to achieve the climate that is required, and you can further save energy. A special sensor in the air conditioner system without an external unit will indicate that it is time to empty the drain pan. If you do not save the structure from condensed moisture, the device will automatically turn off. The absence or presence of the described functions affects the cost of a particular model.Low cost devices have only electromechanical control devices.
More about the device: filters
Monoblocks are equipped with filters for basic cleaning. They need to be removed and rinsed with water from time to time. If we are talking about thin coal and similar barriers, then they are equipped with more expensive models. Such filters periodically change, the frequency will depend on the pollution of that part of the atmosphere, which is processed by air conditioning.
Principle of operation
Before you buy an air conditioner for your home, you must understand how it works. It is expressed in the transfer of excess heat from the air inside the building to the street. Circulation of air masses by using a fan. The volume of air is driven through the heat exchanger, which operates according to the scheme of the evaporator. When the flows pass through the heat exchanger, they are cooled and the circuit releases heat.
The air conditioner for the house has an air duct that connects to the window in the window opening. Using this node, the heat is removed to the outside. For rooms of country houses such air conditioners are an affordable option for climate technology.Equipment will need only lead to the country and set to a suitable place, including the network. After that, you can enjoy the charm of climate home appliances. However, as a prerequisite for ensuring stable and normal operation of the device, an additional installation of the heat sink tube appears.
The beauty of candy bars is that they are easy to install with your own hands. First you need to choose a place and make a hole for fasteners and air ducts. The latter are installed in the next stage, as well as decorative grilles. By mounting the case, you can connect the power supply. If you wish, you can upgrade the finished glass unit, dividing it into two parts. One of them will be a sandwich panel with a hole for the pipe. However, this option is not cheap.
Description of wall air conditioning Climer VX 25
If you decide to purchase a mobile climatic equipment, you can pay attention to the model mentioned above. The cooling power is 2.64 kW, the heating power is 2.78 kW. Overall dimensions of installation: 580 x 1000 x 230 mm.This air conditioner weighs 40 kg without an external Climer unit.
His work, you can manage with the remote. The noise level at work reaches 36 dB. It is possible to purchase the described wall-mounted air conditioner without an external unit for 74,500 rubles.
Such air conditioners have recently become increasingly popular due to several factors. Among them should be highlighted: aesthetic appearance, ease of installation, minimizing the length and number of connecting elements, low cost and ease of maintenance.
