Water source heat pump air conditioning system works and what are the advantages?
With the development of science and technology, air conditioning compressors have gradually been replaced by other starting equipment. Air water source heat pump is a relatively new air-conditioning start equipment, both heating and cooling. Xiaobian now to introduce the air conditioning heat pump air conditioning system works and what are the advantages? Air source heat pump heating principle Air conditioning water source heat pump air conditioning system Introduction Water source heat pump is a use of underground shallow geothermal resources (including groundwater, soil or surface water, etc.) can both heating and cooling energy efficient air conditioning system. Water source heat pump by entering a small amount of high-grade energy (such as electricity), to achieve low-temperature heat transfer to high temperature. In winter, respectively, as a heat pump heat source and the summer air-conditioning cold source, that is, in winter, the heat to "take out" to increase the temperature, the supply of indoor heating; Summer, the indoor heat removed, release To the ground can go. Usually water source heat pump consumes 1kW of energy, users can get more than 4kW of heat or cold. Advantages of air conditioning water source heat pump air conditioning system 1, water source heat pump is the use of the Earth's water storage of solar energy resources as a source of cold and heat, energy conversion heating air conditioning system. Among the available water bodies are groundwater or rivers, rivers and lakes that are part of the surface, and oceans. Surface soil and water body is not only a huge solar collector, collecting 47% of the solar radiation energy, more than 500 times the annual energy use of human beings, but also a huge dynamic energy balance system, the surface of the soil and water natural To maintain the relative balance of energy acceptance and divergence. This makes it possible to utilize almost infinite solar energy or earth stored therein. So, water source heat pump is a kind of technology that uses clean renewable energy. 2, water source heat pump unit available water temperature in winter is 12 ~ 22 ℃, the water temperature is higher than the ambient air temperature, so the heat pump cycle evaporation temperature increases, energy efficiency also increased. The summer water temperature is 18 ~ 35 ℃, the water temperature is lower than the ambient air temperature, so the cooling condensation temperature decreases, making the cooling effect is better than the air-cooled and cooling towers, unit efficiency. According to the estimation of the U.S. Environmental Protection Agency (EPA), designing and installing a good water source heat pump can save 30% to 40% of the heating and cooling air-conditioners on average. 3, the water temperature is relatively stable throughout the year, the scope of its fluctuations is much smaller than the air changes. Is a very good heat pump heat source and air conditioning cold source, water temperature is more constant characteristics, making the heat pump operation more reliable and stable, but also to ensure the system's efficiency and economy. There is no air source heat pump in winter defrost and other difficult issues. 4, water source heat pump using electricity, electricity itself is a clean energy, but in power generation, consumes primary energy and lead to emissions of pollutants and CO2 greenhouse gases. Therefore, the pollution of energy-saving equipment itself is small. The power consumption of well-designed water-source heat pump units is equivalent to a reduction of more than 30% compared to air-source heat pumps, which is equivalent to a reduction of more than 70% when compared to electric heating.
