Air-cooled heat pump works

The air-cooled heat pump is a component of a home central air-conditioning unit. In simple terms, the air-cooled heat pump works on the basis of a compression-type refrigeration cycle, which draws or discharges heat energy from the atmosphere through fans. Let's take a closer look at the working principle of the air-cooled heat pump.

The principle of air-cooled heat pump: air-cooled heat pump unit is the host of the air-conditioning system, because the use of air-cooled condenser does not require a cooling tower, while the evaporator is water-cooled, in the summer to provide cold water cooling, winter heating, provide hot water, fan The coil is the end device of the air-conditioning system. It is installed in the room as if the water is raised from a low position to a high position and a water pump is used. A heat pump can pump heat from a low temperature to a high temperature. So the heat pump is essentially a kind of heat lifting device. The function of the heat pump is to extract heat from the surrounding environment and pass it on to the heated object (the object with higher temperature). Its working principle is the same as that of the chiller. The air-cooled heat pump working against the Carnot cycle has a lower capacity than the air source heat pump. Its inlet and outlet water temperature is about 5 degrees Celsius (most of the company's setting parameters), and the temperature difference between the inlet and outlet water of the air source It reaches 40 degrees Celsius.

The air-cooled heat pump unit is used in conjunction with a fan coil. The former provides cold water or hot water, while the latter uses cold or hot water to exchange cool air or hot air. We can visualize the air-cooled heat pump unit as the brain of a central air-conditioner. If the brain is not working, the central air-conditioning system will lose all its functions and the system will stop operating.

With the gradual development of science and technology, we will be exposed to more and more new high-tech products. If we can understand the working principle of them, it will help us to use them better.
