Method for increasing refrigerating quantity and reducing power of air conditioner and air conditioning device

Abstract

In the invention, a throttle device in the air conditioner refrigeration circuit is set in the room unit. A section of a high-pressure copper pipe in the front of the throttler is immersed into a condensed water holding tray of the room unit and is cooled to increase the super cooling degree of the condenser, so as to increase the refrigerating output.

Description

technical field [0001] The invention relates to an air conditioner and a method for increasing the cooling capacity and reducing power of the air conditioner. Background technique [0002] In the refrigeration system, the increase of subcooling can increase the cooling capacity. attached figure 1 The pressure enthalpy diagram for the refrigeration principle. According to the pressure-enthalpy diagram of the refrigeration principle, it can be seen that the compressor sucks a low-pressure and low-temperature gaseous refrigerant a, which is compressed into a high-temperature and high-pressure gaseous refrigerant b; b is condensed by a condenser to become a high-pressure and medium-temperature liquid refrigerant c; c is further cooled , becomes d with constant pressure and lower temperature; c-d is called the subcooling cooling process, also called subcooling degree, and the cooling capacity will increase correspondingly when the subcooling degree increases. Because of the in...

Problems solved by technology

At present, there are many common ways to increase the degree of subcooling, such as an air-conditioning device disclosed in Chinese patent 96245187.8, a counter-flow liquid-liquid heat exchanger is added before the restrictor as a subcooler, which can effectively improve the degree of subcooling , but this design is aimed at cold storage/heat air conditioning devices, using the water in the cold storage tank to cool the refrigerant before throttling, which is not suitable for general household air conditioners, and has a complicated structure; Ground water or indoor tap water is used for cooling, but the premise of this device is to place the outdoor unit indoors, and it needs to use a large amount of water, and the cooling system pipeline is complicated

In addition, 02267929.4 discloses a heat recovery device for a multi-connected air-conditioning system. This device first seals the high-pressure liquid refrigerant copper tube before entering the capillary restrictor and enters the bottom of the gas-liquid separator and passes through the upper part o
