Description
技术领域technical field
本发明涉及一种除霜装置，特别涉及一种空气源热泵热水器蒸发器的除霜装置。The invention relates to a defrosting device, in particular to a defrosting device for an evaporator of an air source heat pump water heater.
背景技术Background technique
空气能热泵热水器是把空气中的低温热量吸收进来，经过压缩机压缩后转化为高温热能以此来加热水温。换热工质在蒸发器进行吸热蒸发，因此容易在翅片及蒸发管结霜，热水器运行前需进行除霜工作。现有的除霜方式包括采用四通阀换向除霜以及压缩机排气除霜，四通阀换向除霜具有良好的除霜效果，速度快，但是由于冷水流入储水罐造成水温降低，使用体验不佳。压缩机排气除霜不会降低水温，但是除霜时间长。目前也有混合两种模式的除霜技术，但是整体装置结构复杂，对控制系统要求较高。The air energy heat pump water heater absorbs the low-temperature heat in the air and converts it into high-temperature heat energy after being compressed by a compressor to heat the water. The heat-exchange working medium absorbs heat and evaporates in the evaporator, so it is easy to frost on the fins and evaporator tubes, and the water heater needs to be defrosted before running. The existing defrosting methods include four-way valve reversing defrosting and compressor exhaust defrosting. The four-way valve reversing defrosting has a good defrosting effect and fast speed, but the water temperature drops due to cold water flowing into the water storage tank. , poor user experience. Compressor exhaust defrosting will not lower the water temperature, but the defrosting time is long. At present, there is also a defrosting technology that mixes the two modes, but the structure of the overall device is complex, and the requirements for the control system are relatively high.
