Split Heat Pump Systems

Water from a height to the lower temperature, heat from the transfer to the low temperature object, this is the law of nature. However, in real life, in order to agricultural irrigation, water and other life needs, people use water from low to high. Similarly, in today's increasingly tense energy, in order to recover normally pumped into the atmosphere, low temperature split heat pump systems discharged into the river in low temperature hot water in the heat, heat pump is used to transmit the heat energy of low temperature of objects in high temperature object, then the object of high temperature to heat water or heating, the heat can be fully utilized.

The Principle Of Solar Water Heater For Pools
The principle of heat pump and air conditioner, such as refrigerators working principle is basically the same, the flow through the media (formerly general as Freon, now replaced by substitute for Freon sky) in the evaporator, compressor, condenser and expansion valve and other parts in the gas phase change (boiling and condensation) cycle to transfer the heat low temperature object high temperature object. The specific working process of solar water heater for pools as follows: superheated liquid media in the evaporator absorbs heat low temperature object, evaporated into gas media. Evaporator of gas media hydraulic compressor compression is in high temperature and high pressure gas media. High temperature and high pressure gas medium in condenser, heat release to the high temperature object, at the same time itself into a high-pressure liquid media. High pressure liquid media in the expansion valve in vacuum, and then into a superheated liquid media, into the evaporator, circulating the initial process.

Heat pump Performance
Heat pump performance is generally with the coefficient of performance (COP) to evaluate. Coefficient of performance defined as low temperature object to high temperature and body heat and need power than. Usually pump performance coefficient is about 3-4, that is to say, the heat pump can itself be required energy 3 to 4 times the heat from low temperature object is transmitted to the high temperature object. Now Europe and the United States and Japan are competing in the development of new type of heat pump. According to the report model heat pump performance coefficient can be 6 to 8.If this value can be popular words, which means that energy will be used more effectively. Heat penetration will dramatically improve. The heat pump maximum output temperature is 110 degrees. Above this temperature may make the media the danger of decomposition. As a result of freon in Earth's atmosphere ozone damaging effects, in order to protect the ecological environment on the earth, in addition to improve the heat pump into the coefficient, the efficient use of energy, national science has committed to a new type of freezing media development. At present, instead of Freon media applications.
