Description
技术领域technical field
本发明涉及热水除霜制冷系统，具体的说是一种利用压缩机排气余热得到热水用于除霜的制冷系统。The invention relates to a hot water defrosting refrigeration system, in particular to a refrigeration system which utilizes exhaust waste heat of a compressor to obtain hot water for defrosting.
背景技术Background technique
制冷温度低于0℃的制冷系统，冷却空气的蒸发器空气侧都会结霜，过厚的结霜会增大换热管的传热热阻，导致蒸发温度降低，制冷系统制冷量减小，COP降低。因此，当蒸发器表面结霜达到一定厚度的时候(结霜厚度不应导致蒸发器的传热系数下降10％)就应该除霜。In the refrigeration system whose refrigeration temperature is lower than 0°C, frost will form on the air side of the evaporator of the cooling air. Too thick frost will increase the heat transfer resistance of the heat exchange tube, resulting in a decrease in the evaporation temperature and a decrease in the cooling capacity of the refrigeration system. The COP is lowered. Therefore, when the frosting on the surface of the evaporator reaches a certain thickness (the thickness of the frosting should not cause the heat transfer coefficient of the evaporator to drop by 10%), it should be defrosted.
在采用风冷式冷凝器的制冷系统中，常采用的除霜方法是热气融霜、电融霜、热水冲霜。热气融霜是压缩机排出的高温气体进入蒸发器进行融霜；电融霜是利用电加热器对蒸发器盘管进行加热融霜；热水冲霜是把热水喷淋在蒸发器盘管上进行融霜，夏季时，热水容易获得，冬季则需要加热得到。这几种除霜方法都需要消耗大量能量，增加制冷系统能耗。In a refrigeration system using an air-cooled condenser, the commonly used defrosting methods are hot gas defrosting, electric defrosting, and hot water defrosting. Hot gas defrosting is that the high temperature gas discharged from the compressor enters the evaporator for defrosting; electric defrosting is to use an electric heater to heat and defrost the evaporator coil; hot water defrosting is to spray hot water on the evaporator coil In summer, hot water is easy to obtain, but in winter, it needs to be heated. These defrosting methods all need to consume a lot of energy and increase the energy consumption of the refrigeration system.
传统制冷系统除霜耗能大，运行经济性低，所以有必要设计和开发一种低能耗的除霜制冷系统。The traditional refrigeration system consumes a lot of energy for defrosting and has low operating economy, so it is necessary to design and develop a defrosting refrigeration system with low energy consumption.
