Types of heat pumps

[Brenda Bailey]

According to the kind of warmth source, it is divided into air supply warmth pump, water supply warmth pump, floor supply warmness pump, twin supply warmth pump (a combination of water supply warmness pump and air supply warmness pump) and so on.

Air source heat pump
During the operation of the air supply warmth pump, the evaporator absorbs warmth from the ambient thermal strength in the air to evaporate the warmth switch working medium. After the working medium vapor is compressed by means of the compressor, the stress and temperature rise. When the tube is connected, the condenser condenses into a liquid, transferring warmth to the water in the air supply warmness pump water storage tank.
Working medium of warmth pump
The air-source warmth pump warmness switch medium is a one of a kind substance with a boiling factor of minus forty ° C and a freezing factor of minus one hundred ° C below everyday pressure. This substance is liquid when it is cold, however it can be without difficulty evaporated into gas, and vice versa. In true operation, the evaporation restrict temperature of the warmness switch working medium in the air supply warmness pump is about minus 20 ° C, so the ambient temperature of 5 ° C is additionally "hot" for such a low temperature, even snow temperature, such as zero ° C. In contrast, it is additionally hot, so it can nonetheless alternate some thermal energy.

Water source heat pump
Shallow water sources on the earth's floor (generally inside a thousand meters), such as groundwater, floor rivers, lakes, and oceans, take in the great radiant electricity from the solar into the earth, and the temperature of the water sources is typically very stable. The working precept of water supply warmness pump technological know-how is: with the aid of inputting a small quantity of high-grade power (such as electrical energy), the low-temperature warmth electricity is transferred to the high-temperature level. The water physique is used as a warmth supply for heating by using a iciness warmness pump and a bloodless supply for air conditioning in summer. That is, the warmness in the constructing is "taken out" in summertime and launched into the water body. Because the temperature of the water supply is low, the warmth can be efficaciously taken away to obtain summer season The reason of cooling the building's interior; in winter, it is to "extract" warmness electricity from the water supply thru the water supply warmth pump unit and ship it to the constructing for heating.

Ground supply warmth pump
Ground supply warmness pump is a type of high-efficiency energy-saving air-conditioning tools that can use warmth and refrigerate by means of the usage of shallow geothermal sources (also known as floor energy, inclusive of groundwater, soil or floor water, etc.). The ground source heat pump realizes the switch from low-temperature warmness strength to excessive temperature warmness electricity by using inputting a small quantity of excessive grade power (such as electricity). The floor power is used as a warmness supply for heating by using the warmness pump in iciness and as a bloodless supply of cooling in summer. That is, in winter, the warmth from the floor power is taken out and the temperature is multiplied to grant indoor heating. In summer, the indoor warmth is taken out and launched to The floor can go. Ground supply warmth pumps typically eat 1kWh of energy, and customers can get extra than 4kWh of warmth or cold.

High temperature air electricity heat pump

The high-temperature air strength warmness pump actually refers to a warmth pump (ie, a high-temperature drying warmness pump) whose heating water temperature is greater than 60 ° C (ie, high-temperature warm water) or whose air temperature can attain above eighty ° C. Compared with the traditional warmth pumps on the market today, the temperature of traditional warm water is typically beneath 55 ° C, and the new technology of high-temperature air warmth pumps can produce high-temperature warm water of about eighty five ° C, which can be used for electroplating and pasteurization Butchery, glass cleaning, printing and dyeing industries.
