Comparison of sewage source heat pump ground source heat pump and air source heat pump

Sewage source heat pump system compared with the traditional advantages of heat exchanger Sewage source heat pump is the city's sewage as a cold and heat source for indoor cooling heating, consumption of a small amount of electricity through the sewage source heat pump system within the heat pump to do work, the sewage In the cold and heat can be delivered to the interior to meet human needs. Sewage source heat pump system can both heating and cooling, can be said to be a dual-use, to a large extent, help modern enterprises to reduce operating costs, and the use of sewage as a building heating and cooling energy, with the traditional rely on coal and Compared to groundwater heating and cooling, energy saving and environmental protection. Sewage source heat pump system compared with air source heat pump, electric boiler coal heating, ground source heat pump heating and cooling: 1. Compared with air source heat pump system, sewage source heat pump system compared with air source heat pump to avoid the air source heat pump need to be timed in winter Of the frost and defrosting problems, as the internal temperature of the sewage relatively speaking, all year round in a relatively stable turntable, so the sewage source heat pump system performance is relatively stable. Under normal circumstances the heat pump cooling coefficient can reach 5 to 6, the cooling coefficient of heating is in the case of the same hot and cold energy consumption than the air source heat pump to save 42% -45% .2 with the groundwater Compared with sewage source heat pump system, groundwater source heat pump system has the advantage of using wastewater as energy source and thus avoiding the extraction of water resources from groundwater, so there is no need to waste a lot of energy and material resources to consider and solve the problem of wastewater recharge The problem, which solved the drilling infrastructure at the same time, but also be able to save the late pumping and waste water recharge operating costs. But also to avoid problems such as the destruction of groundwater resources caused by improper recharge. Compared with electric boilers and coal-fired boilers compared with the electric boiler, the sewage water source heat pump is driven by electricity to do the internal heat pump work, produce the same hot and cold energy, the power consumption compared to electric boilers can Nearly 65% ​​savings in electricity, compared with fuel boilers have to save 1/2 energy. Conventional boiler combustion produces a large amount of harmful gas and therefore easily causes damage to the atmosphere. However, the sewage water source heat pump system uses sewage for heat exchange and is more environmentally friendly and energy-saving than the traditional boiler, and also has good air pollution due to the use of a conventional boiler The environmental effects. Sewage source heat pump system is generally used in two ways, one is the direct use, that is, the sewage directly into the heat pump unit after the heat transfer in the hot and cold energy to the interior; but indirect use, indirect use is usually Sewage flows through the heat exchanger for the first heat exchanger, heat transfer in the heat pump after the heat will be delivered to the room. If the sewage directly through the sewage heat pump heat exchanger, easily lead to heat pump plugging, long-term will result in reduced heat transfer efficiency; to take indirect Renrink centrifugal sewage heat exchanger, while improving heat transfer efficiency but also effectively avoid The sewage stains in the heat exchanger caused by congestion, can be described as double benefit.
