Air-cooled heat pump works

Air-cooled heat pump is an integral part of the household central air conditioning unit, in simple terms air-cooled heat pump works based on the compression refrigeration cycle, through the fan to draw or discharge heat from the atmosphere. Next, let's look at the working principle of air-cooled heat pump in detail. Air-cooled heat pump works: Air-cooled heat pump air-conditioning system is the host system, as the use of air-cooled condenser does not require cooling towers, while the evaporator is water-cooled, summer cooling to provide cold water, hot water in winter to provide heat, fans Coil is the end of the air-conditioning system, installed in the room as the water from the lower to the top and the use of water pumps, the heat pump can be used to draw heat from low to high temperature. Therefore, the heat pump is essentially a heat lifting device. The function of the heat pump is to draw heat from the surrounding environment and transfer it to the heated object (the object with a higher temperature), which works in the same way as the refrigerator and is in accordance with Reverse Carnot cycle work, air-cooled heat pump relative to the air-source heat pump his ability to be lower, his access to water temperature is about 5 degrees Celsius (most of the company's set parameters), while the air source out of the water temperature difference Reached 40 degrees Celsius. Air-cooled heat pump units are used in conjunction with fan coils, the former providing cold water or hot water, the latter passing cold or hot water through heat exchange, drawing cold or hot air. We can vividly compare an air-cooled heat pump unit to the brain of a central air conditioner. If the brain does not work, the central air conditioner 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 how they work better for our better use of some help.
