Many air source heat pumps are installed on a family basis. The air source heat pump solves the problems of heating and hot water use for these families in winter, and can also bring coolness to the family in the hot summer.
Many people think that there is not much difference between air source heat pump and air conditioner, but the prices are not the same. They think that the air source heat pump prices are a bit expensive. In fact, there is still a big difference between air source heat pumps and air conditioners.
1. Working principle
The EVI air source heat pump uses electricity to drive the heat pump compressor to work and compress the low-temperature refrigerant into a high-temperature refrigerant. The high-temperature refrigerant exchanges heat with water through the hot water heat exchanger. After the heat exchange, the high-temperature refrigerant is depressurized by the expansion valve and then absorbed by the evaporator. The heat in the medium, the refrigerant after absorbing heat is sucked in by the compressor, continuously absorbing heat from the air, and dissipating heat on the heat exchanger side to heat the cold water. The heat absorbed by the water is the sum of the heat produced by the compressor and the heat absorbed by the air by the refrigerant.
The air conditioner also uses electric power to drive the air conditioner compressor to compress the low temperature refrigerant into a high temperature refrigerant. The high temperature refrigerant is dissipated by the evaporator. The air conditioning main body fan discharges the heat to the outside. The heat dissipated high temperature refrigerant is reduced by the expansion valve and evaporated by the air conditioner indoor unit. The compressor absorbs the heat in the air and reduces the indoor temperature. The refrigerant after absorbing the heat is sucked by the compressor. In this way, the heat is continuously discharged from the indoor to the outdoor air, and the heat is absorbed from the indoor to achieve the purpose of reducing the indoor temperature.
2. Use comfort
Air conditioners always use refrigerant as the medium, and although air source heat pumps also use refrigerant to transfer heat, in the final heat exchange stage, air source heat pumps use water for heat exchange. That is, the air conditioner is a fluorine system cycle, and the air source heat pump is a water system cycle.
Whether it is cooling or heating, the fluorine system will absorb a large amount of moisture from the air, causing the air to be dry. In this environment for a long time, people will feel hoarse with dry mouth, especially in winter.
3. Operating expenses
The air source heat pump uses air as a source of cold and heat to provide heating, cooling and domestic hot water to the indoor space.
4. Use function
The most powerful function of the air conditioner is cooling. If heating is required in winter, it will not only consume a lot of electricity, but will also easily cause physical discomfort when people live in this environment for a long time. Therefore, air conditioning is not the best heating method, so few people use air conditioning as a heating method.
The air source heat pump adopts low temperature EVI technology, which can increase the heating energy efficiency by 30% in cold weather. It not only has the cooling function, but also has the functions of heating and domestic hot water supply. It truly realizes one machine with powerful functions.
