Improve the potential of machinery and equipment - "pump"; pump usually start to get air, water or soil nature of low-grade heat, acting through the power, and then again it may be used to provide high-grade heat.
Works
Water flows from the lower height, the heat produced by high-temperature materials delivered to the whole body hypothermia, which is a natural law. However, in real life, the need for irrigation, domestic water, etc., people use to pump water from the lower height. Similarly, in today's increasingly tense energy, usually in order to recover the low temperature heat into the atmosphere, the heat discharged to the river in the low-temperature hot water, heat pumps are used to transfer heat cold objects in the hot object, and then the high temperature heating the object to heat water or to make full use of the heat.
According to the Throttle Body Kero learned works heat pump system works with the refrigeration system is consistent. To find out the heat pump works, we must first understand the working principle of the refrigeration system. Cooling System (compression refrigeration) generally consists of four components: a compressor, condenser, throttle, evaporator. The working process is: temperature low-pressure liquid refrigerant (e.g. Freon), from the first evaporator in the low temperature heat source (e.g., chilled water) and the endothermic gasification of low pressure vapor. The refrigerant gas is then compressed in the compressor into high temperature high pressure steam, the high-temperature high-pressure low-temperature gas in the condenser is a heat source (e.g., cooling water) cooled condensed into high pressure liquid. Then by throttling element (capillary, thermal expansion valve, electronic expansion valves, etc.) into a low-temperature low-pressure throttling liquid refrigerant. This completes one cooling cycle.
The general performance of the heat pump refrigeration coefficient (COP coefficient of performance) to evaluate. Cryogenic refrigeration coefficient is defined by the object passed to the object than the power of the high-temperature heat and needed. Cooling the heat pump coefficient of usually 3-4, that is, the heat pump can be 3-4 times the thermal energy required for its object transfer from a low temperature to a high temperature object. Therefore, the heat pump is essentially a lifting device, the work itself consumes little energy part, able to be extracted from the surrounding medium (water, air, soil, etc.) in 4-7 times the power of the apparatus for use elevated temperatures, This is the reason for heat energy. Europe and Japan are racing to develop a new type of heat pump. It is reported that a new type of heat pump refrigeration coefficient can be 6-8. If this value can then be universal, which means that energy will be more effectively utilized. Heat penetration will also get an amazing improvement.
Ground source heat pump is a pump, is the earth or water as heat source for the buildings cool in air conditioning technology, ground source heat pump only between the earth and the interior "transfer" of energy. Using minimal power to maintain the desired indoor temperature. In winter, one kilowatt of electricity or water in the soil 4-5 kW of heat into the room. In the summer, the process is reversed, the indoor heat is transferred to the soil or water pump, air in the room to get cool. |
