New air source heat pump system of energy store for heat flux defrost and it's experimental study

Based on the theory of rational energy utilization in time and space, in order to solve the problem of poor reliability of defrosting and worsen indoor environment because of defrosting, a new air source heat pump system of heat flux defrosting is presented. An energy store equipment of phase change is added to the system to store surplus heat when heap pump runs in high efficiency and the heat is used as low grade energy for defrosting. So the problem of the energy lacking for heat flux defrosting is thoroughly solved. The test board of the new system is introduced and the compared experiment of defrosting characteristic of the traditional system and the new energy store system are carried on. The result proved the advantage of the new air source heat pump system of energy store for heat flux defrosting.
