Tip 1: How the air conditioner works

The air conditioner is a device forchanges in air temperature in the room. It consists of an external and internal blocks, through which a special substance moves, capable of collecting and giving off heat.

The operation of the air conditioner is based on a changethe aggregate state of a special substance under the influence of temperature and pressure. This substance is most often freon, which can pass from the gaseous state to the liquid. To understand the principle of the air conditioner, you must first familiarize yourself with its device.

How does the air conditioner work?

Modern air-conditioners are equipped with electronicblock that allows remote control. Isolate the outer and inner blocks. The outdoor unit consists of a fan, a condenser, a compressor, a control board, a four-way valve, and a filter. The fan is required for blowing the condenser. The condenser is a radiator in which freon is cooled and condensed. When air passes by it, it heats up. The compressor compresses Freon and ensures its movement along the refrigerating circuit. The four-way valve is in the condensers, which can heat the air. It changes the direction of the freon movement. The indoor unit then starts to work for heating, and the outdoor unit for cooling. The filter is in front of the compressor inlet, its function is protective. The outdoor unit is closed with a lid. The indoor unit of the air conditioner is a front panel, a coarse filter, fine filters, a fan, an evaporator, a control board, blinds. Air comes through the front panel. The coarse filter is a plastic mesh for the retention of relatively large objects. Fine filters remove smells, detain fine dust and bacteria. The fan is directed to circulate cleaned and heated / cooled air in the room.

How the air is cooled and heated by an air conditioner

The evaporator heats the freon, after which itevaporates. When air passes through the evaporator, it cools. The blinds regulate the direction of the air flow, their position can be controlled remotely. The indoor and outdoor units are connected by copper pipes. In the control board there is an electronics unit with a microprocessor. The air conditioner does not by itself produce cold or heat, it is engaged in transferring it from the room to the street or vice versa. When evaporating, freon selects heat, condensing - gives. The condensation process is a return from the gaseous state to the liquid state. In the cooling mode, freon evaporates in the indoor unit and condenses in the outdoor unit. When heating is the other way round. So heat is transferred from one environment to another.

Tip 2: How to repair an air conditioner

Air conditioning is a rather complex technicalA device that requires compliance with the relevant rules when it is used. Like any technical system, the air conditioner can fail if used incorrectly or for other reasons. If the appliance does not work properly, do not despair. Some kinds of malfunctions of the conditioner you can try to eliminate independently, without participation of the expert.

Instructions

The most common faultconditioner - when the filter of its internal part is completely hammered. Figuratively speaking, the device ceases to "breathe", there is a decrease in the supply of cold or heat, jamming of the engine, abnormal operation of the fan. To prevent these malfunctions, regularly clean the filters by following the instructions that came with the device.

Quite often there is another, "imaginary"a malfunction due to improper use of the remote control. Pay attention to the value of the temperature set in the device and the one that is actually present in the room. In order for the cooling mode to work correctly, set the temperature to be below room temperature. If you want the air conditioner to work on the radiation of heat, set the thermostat above room temperature.

If there is a termination of allfunctions on the display or the air conditioner panel, then there is probably a malfunction associated with the control card. Sometimes this situation can be corrected by using the "Reset" function or by completely disconnecting the device from the network for several minutes. If these measures do not lead to the unblocking of the air conditioner, the intervention of a qualified repair technician will be required.

If there is a water leak from the air conditioner, you canconclude that the drainage system is clogged. To eliminate blockage, take the drain pipe that comes out of the air conditioner into the street, and carefully blow it out. As soon as water comes out of the tube, it means that the blockage is eliminated.

One of the true signs of a lack of freon inThe cooling system of the air conditioner is frost covering the copper tube of large diameter on the outside of the device. The second sign of such a malfunction is that the air conditioner generates insufficient cold with normally cleaned filters and a properly working engine. You can not rectify such a malfunction, so contact the service center to solve the problem with a specialist.
