The operation of an air-water heat pump

An air-water heat pump is an efficient heating and cooling system. It works in the same way as other heat pump systems, but in this system air is used as the heat exchange medium.

The principle of an air-water heat pump is comparable to that of an air conditioner. In other words: the air-water heat pump is similar to an air conditioner and both use the reverse Carnot cycle.

Wikipedia: The Carnot process or Carnot cycle is an ideal thermodynamic loop process in which all heat is supplied at a high temperature  and removed at a low temperature . As a result, the largest possible part of the heat supplied is converted into work.

Air-water heat pumps offer many advantages over traditional heat pumps. First, it provides efficient heating and cooling without the need for additional fuel. This lowers energy bills and reduces the negative impact on the environment.

In addition, air-water heat pumps can provide a more even and comfortable temperature distribution. Because they radiate heat throughout the room, they ensure that no cold or hot spots arise. This results in more stable indoor temperatures and provides a more pleasant living, working and learning environment.

Summer cooling

The air-water heat pump maintains the comfortable temperature of the room through the water circulation system. When the fan coil, underfloor heating or low temperature radiator is switched on, the fan coil, underfloor heating or low temperature radiator absorbs the heat in the room into the water. The circulating water in the pipe rising to 25℃-35℃ returns with the absorbed heat. After the heat pump compressor reaches the heat pump, it performs heat exchange to release the excess heat or use it for heating sanitary water. At this time, the circulating water temperature in the pipeline can be reduced to 7°C, then the water pump promotes circulation to bring the cold energy to the heat pump host. At this time, the exhaust air temperature of the fan coil unit is only 12℃-15℃. The purpose of cooling is achieved through heat exchange with the indoor air.

Winter heating

The air-water heat pump absorbs low-quality heat from the air, converts it into high-temperature heat via the compressor and then transfers the increased heat to the water via the heat exchanger. It continues to work until the water temperature reaches the heating demand, and finally the underfloor heating (radiator, fan coil unit) distributes the heat in the water to the room, completing the heating of the room in winter.

In short, the air-to-water heat pump is a highly advanced heating and cooling system with many advantages, such as high efficiency, environmental protection and uniformity, and can bring more comfort and convenience to our lives.
