What is the principle of air conditioning in winter and summer based on? What do users need to know about the proper operation and purchase of HVAC equipment?
The principle of operation of the air conditioner winter-summer
When cooling and heating the air conditioner uses the same scheme. It is based on heat transfer between the liquid and the environment during the transition of the first from one physical state to another.
The main "working" body in this process is the radiator or heat exchanger. There are two of them, one is needed for boiling the refrigerant with heat absorption, the other for condensation with heat transfer. In accordance with the functions, heat exchangers are called a condenser and an evaporator. And only a change of functions with each other determines the cooling or heating of the air conditioner.
In summer, the air conditioner operates in cooling mode: the outdoor module functions as a condenser, and the internal one as an evaporator.
In winter, the opposite is true. And you should remember: there are no special heating elements in the air conditioner for winter and summer.
Having carefully studied the technical data, we notice that when the air conditioner is in operation in the summer, a little less energy is consumed than during heating. This happens because when heated, the refrigerant pressure increases, the load on the compressor increases, which takes more electricity.
Features of the air conditioner winter-summer
Equipment difficulties begin in early autumn or cold summers. The air conditioner needs to be switched to heating. The button on the remote control is pressed, the LEDs are activated, but the fan is standing. Most users start to panic.
She is in vain. Equipment needs a few minutes to switch to heating mode.
The “hot start” mode starts. These minutes are needed for the heat exchanger of the indoor unit to heat up.
Air conditioner price winter-summer
In autumn, spring and cold summers, an air conditioner operating in two modes is very practical.
Therefore, the demand for such models is much higher, despite the cost. The price of air conditioner winter-summer is not less than 150 cu higher than the similar in power "pure summer" apparatus. The ability to change the functions of the blocks is carried out by electronics and a number of mechanical spare parts. They cost money and the higher the class of air conditioners, the greater the difference between cooling and dual-mode models.
If the price of the winter-summer air conditioner is too low, you should refuse to buy this device.
