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...
