Water dispenser

Abstract

A water dispenser comprises a compressor, a pre-heating tank, a first heat exchanger, a heating tank, a cold-hot water heat exchanger, a warm water tank, a fourth heat exchanger, an ice water tank, an expansion valve, a second heat exchanger and a third heat exchanger, wherein the compressor, the pre-heating tank, the first heat exchanger, the heating tank, the cold-hot water heat exchanger, the warm water tank, the fourth heat exchanger, the ice water tank, the expansion valve, the second heat exchanger and the third heat exchanger are communicated with each other through pipelines, and wherein the compressor includes a first end and a second end; the first end of the compressor is connected to a second end of the first heat exchanger; the first heat exchanger is wound around the outer wall of the pre-heating tank; a first end of the first heat exchanger is connected to a second end of the second heat exchanger; a first end of the second heat exchanger is connected to a second end of the expansion valve; a first end of the expansion valve is connected with a second end of the fourth heat exchanger; and the forth heat exchanger is wound around the outer wall of the ice water tank.

Description

[0001] This application is a divisional application, the application number of the original application is 201210156076.4, the application date is May 18, 2012, and the title of the invention is "heat pump air-conditioning system and water dispenser". technical field [0002] The invention relates to a water dispenser using a heat pump air conditioning system. Background technique [0003] The most basic components in general air-conditioning equipment include four major components: evaporator, compressor, condenser and expansion valve, which are connected in sequence by pipelines to form a cycle of cooling in the evaporator and heating in the condenser system. According to different functions, different products are produced, including air conditioners, refrigerators, air conditioners, ice water hosts, refrigerators, heat pump water heaters, etc. [0004] see figure 1 It is a system schematic diagram of the refrigerant cycle of an existing air conditioner. The cycle syste...

Problems solved by technology

The cooling of the evaporator 1 enters the room to provide indoor cold air. The problem is that when the temperature of the hot water in the hot water storage tank 6 is higher, the high-pressure and high-temperature gaseous refrigerant cannot completely release the heat of condensation, which will make the high pressure of the refrigerant circulation system higher. The cooling capacity of the evaporator 1 will be reduced

Furthermore, another problem is that when hot water is produced in winter, the cooling of the evaporator 1 must be discharged to the outside, and because the outdoor temperature is low in winter, the low pressure of the refrigerant in the evaporator 1 will be lower than that during normal operation. The high-pressure refrigerant will be lower than the high-pressure refrigerant in normal operation, and the temperature of the hot water produced will naturally be lower than that in normal operation
