Abstract

The invention discloses a composite machine set of a steam compression type refrigeration device and a heating device. The purpose of the composite machine set is to create multiple refrigeration and heating cyclic economies. For example, a composite machine of an air conditioner and an air energy heat-pump water heater is in a steam compression type refrigeration system of the air conditioner; a water-cooling type condenser and a wind-cooling type condenser are connected in parallel through three pairs of tees and left and right bidirectional electromagnetic valves; an air energy evaporator is connected in parallel with a water source evaporator; a thermostatic expansion valve is connected in parallel with a capillary tube, and a control system is internally provided with a temperature difference controller and a defrosting temperature controller, so that the composite machine set heats in winter without using auxiliary electric heating, adjusts air in summer and can obtain hot water at 40 DEG C to 60 DEG C without enabling a compressor to be too hot, and the temperature and enthalpy of the colorant can be increased in winter due to the technical innovation mentioned above; the drop between the condensing temperature and the evaporating temperature of the colorant in summer is reduced; and hot water at 60 DEG C can be obtained in the whole year, so that a digital scroll compressor is unnecessary to be purchased. The composite machine set of the steam compression type refrigeration device and the heating device has the advantages of: (1) saving one host; and (2) saving energy and reducing discharge.

Description

technical field

[0001] The invention belongs to the technical field of vapor compression refrigeration equipment and vapor compression heating equipment. Background technique

[0002] Existing air conditioners at home and abroad are designed and manufactured based on the principle of evaporative refrigeration in the evaporator, and the condensation heat released by the refrigerant vapor in the air-cooled condenser is discharged to the atmosphere and is not used; the existing The air source heat pump water heater makes hot water by condensing the refrigerant vapor in the water-cooled condenser, releasing the condensation heat to heat the cold water into hot water at 45°-60°C, which is used for heating in winter and bathing throughout the year, while liquid refrigerant The cooling capacity produced by the evaporation of the air energy evaporator has not been utilized. The global warming in ancient and modern times, especially in modern times, countries around the world have vi...
