Heat pump air-conditioning system with excellent defrosting function

Abstract

The invention provides a heat pump air-conditioning system with an excellent defrosting function, which comprises an indoor unit and an outdoor unit, wherein a defrosting device is mounted at the top of the condenser of the outdoor unit, the defrosting device is divided into an upper layer and a lower layer, the upper layer serves as a water storage layer, the lower layer serves as a water draining layer, an electrical heating rod, a water pump, an electronic water level detecting meter, an electronic water temperature meter and an electromagnetic valve are all arranged inside the water storage layer, the electrical heating rod, the water pump, the electronic water level detecting meter, the electronic water temperature meter, and the electromagnetic valve are all electrically connected with the electric control board of the outdoor unit, the water pump extracts water on a base plate through a water pumping tube, and a first drain hole is formed in the base plate; a second drain hole is distributed on the bottom of the water draining layer, and hot water flows to the condenser for defrosting through the second drain hole. According to the invention, defrosting and heating of the air-conditioning system are enabled to be performed at the same time, during the defrosting process, indoor heating can be performed continuously, indoor hot air is blown out continuously while defrosting is ensured, indoor temperature is more even, user comfort is improved, energy consumption during running of an air conditioner is lowered, and the using cost of users is saved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat pump air conditioning system with good defrosting function. Background technique [0002] With the development of society and the continuous improvement of people's living standards, air conditioners have entered the families of ordinary consumers. At present, according to market information surveys, consumers have higher and higher requirements for the comfort brought by air conditioners, especially the heating effect, which is one of the issues that northern users are more concerned about, and it directly affects the living environment of consumers. The existing household air conditioners sold on the market basically complete the defrosting by switching between cooling and heating. The longer duration of the process leads to higher energy consumption of the air conditioner, resulting in a waste of national power resources. Contents of the invention [0003] ...
