Problems solved by technology

[0005] The inventor's patent No. is 00264455.X "a kind of three-purpose machine of double-effect four-season energy-saving heating and cooling air-conditioning and hot water" has introduced the three-purpose machine that adopts a two-way electromagnetic valve and double capillary double one-way valve throttling mechanism, although It has basically realized the idea of ​​not only retaining all the functions of the existing heating and cooling air conditioners, but also energy-saving hot water heating in four seasons. When the machine is only used as a heat pump water heater, the refrigerant will flow into the air-cooled heat exchanger that is not used in this mode during the start-up period, resulting in unstable refrigerant quantity in the circulation loop and incomplete recovery of refrigerant condensation waste heat. In addition, When using the currently commercially available two-way solenoid valve as the refrigerant gas circuit control, the gap between the valve core and the valve body will change due to the difference in expansion under high pressure and high temperature conditions, and mechanical failures are prone to occur

Abstract

The cooling-heating air-conditioning hot water three-purpose machine is characterized by that on the original air-conditioner a countercurrent water-cooling heat exchanger and a three-way two-position reversing electromagnetic valve formed from electromagnetic auxiliary valve and pneuamtic main valve are added, and two energy-saving water-heating control modes of refrigeration mode and heating mode are increased, and a double-loop two-way throttle mechanism also can be adopted or the spiral coil tube-in-tube water-cooling heat-exchanger can be pdlaced in the hot water storage tank, so that said invented three-purpose machine can be used throughout the year, and possesses several functions of refrigeration, heating and providing cold and hot water.

Description

Technical field: [0001] The invention relates to an energy-saving technology for heating and cooling air conditioners and water heaters. Background technique: [0002] Existing heating and cooling air conditioners are only useful in summer and winter, and are generally idle in spring and autumn. This seasonal product makes a large amount of funds backlog for manufacturers and businesses, and the utilization rate of equipment purchased by users is not high, which is a waste of equipment and funds. a waste. The heat that the existing air conditioner discharges to the outdoor environment during cooling in summer is about 3 times of the power consumption of the air conditioner compressor, which is a waste of heat. Household electric water heaters consume a lot of power, have a low utilization rate of power quality, and have an electric-to-heat conversion ratio of less than 1, and they are used all year round. A family of three uses 120 kg of daily hot water to heat from 20°C to...
