The principle of heat pump Sep 27, 2016

Heat pump performance coefficient for general performance (COP COP) to assess. Coefficient is defined as the low temperature high temperature body to body heat and power than required. Usually heat pump Refrigeration coefficient for 3-4, that is, heat pump itself can be 3 to 4 times times the energy required to transfer heat from a cooler body temperature of an object. So the heat pump is essentially a thermal device, work consumes a very small part of its own power, but from environmental media (water, air, soil, etc) 4-7 times the power to extract plant, lifting temperatures, which is why the heat pump energy-saving. America and Japan are racing to develop new types of heat pumps. Reported to a new type of heat pump Refrigeration coefficient can be 6 to 8. If this value to universal, which means that energy will be used more effectively. Heat pump's coverage will also be dramatically improved.

Ground-source heat pump is a heat pump, based on land or water as the heat source for the building is warm in winter and cool in the summer and air conditioning technology, ground source heat pumps is between the Earth and an indoor "transfer" of energy. Use minimum power to maintain indoor temperatures. In the winter, 1-kilowatt of electricity will be 4-5 kW of heat into the Interior in the soil or water. In summer, conversely, indoor heat pump transfers the heat to the soil or water, get cool indoor air. But the underground access to energy will be used in winter. So the cycle, building space and nature into one. With minimal cost to obtain the most comfortable living environment.
