Hot pump type air conditioner set with water heater

Abstract

This invention is about heat exchange device. A kind of heat pump type air conditioner set with water heater includes cooling-water machine set, which is composed of compressor, two-position four way change valve, stop valve, condenser, air conditional heat exchanger, water pump and water circulating system. The character is the water heater, heat exchanger, two-position three way magnetic valve and insulating water tank are set. The inlet of hot water heat exchanger is connected with the outlet of compressor, while the outlet with the inlet of two-position four-way change valve through normally open joint of the said two-position three way magnetic valve. The normally closed joint of the said two-position three-way magnetic valve is connected with pipeline from two-position four -way change valve to air conditioner heat exchanger. The hot water heat exchanger respectively connects to tap water pipe and heat insulating water tank. This invention can open hot water heat exchange for providing heated water during indoor heating state of air conditioner set. Thus, it settles the problems of simple structure, conveniently operating and adequate temperature of hot water.

Description

Technical field: [0001] The present invention relates to heat exchange equipment, in particular to heat pump air conditioning units with water heaters. Background technique: [0002] In the past 20 to 30 years, air-conditioning equipment has not only been widely used in industrial facilities and many public places such as large shopping malls, theaters, stations, docks, warehouses, office buildings, etc. middle. Therefore, air-conditioning equipment is divided into household type and enterprise type according to the user. The former is used for air conditioning in a small area with low power, and the latter is generally used for air conditioning with high power suitable for a wide range of spaces. Moreover, with the advancement of technology, air conditioners have developed from simple refrigeration at the beginning to two-way air conditioning equipment that cools in hot weather and heats in cold weather. However, most of the air-conditioning equipment currently only serve...

Problems solved by technology

However, they all have the defects of complex structure, high manufacturing cost, and inconvenient control. For example, the slide valve of the main valve of the four-way reversing solenoid valve used in household air conditioners for cooling or heating needs to be driven by high-pressure gas introduced by the pilot valve. In the invention patent No. ZL200520002821.5, when a two-position three-way reversing solenoid valve connects the compressor with the water tank heat exchanger (that is, when it is in "combined cooling and heating" or "heating"), the four-way reversing solenoid valve There is no high-pressure input at port a of the valve, and the pilot valve cannot introduce high-pressure air to push the spool valve of the main valve to move, so normal reversing cannot be realized. It is necessary to connect the two-position three-way reversing valve to the four-way reversing solenoid valve first. Its a port gets high-pressure gas, performs reversing action, and then restores the two-position three-way reversing valve to make the compressor and the water heater communicate.

And their biggest shortcoming is that they cannot turn on the hot water heat exchanger to provide hot water under the condition of indoor "heating".

In addition, the structure of these air conditioners that can provide hot water is only suitable for low-power household air conditioners. Due to their limited power, the temperature of the hot water is low, and it cannot meet the needs of users very well especially in cold seasons.
