摘要
提出利用制冷剂过冷所放出的热量来解决空气源热泵冬季结霜问题的方法,并给出实现该方法的系统构成。通过计算证明,制冷剂过冷放出的热量远大于除霜需要的热量。
Puts forward one method that makes use of heat output from refrigerant subcooling to resolve the defrosting problem of air-source heat pump in winter,and gives the system configuration for realization of this method. Calculation results prove that the heat output from refrigerant subcooling is far greater than the need for defrosting.
