Abstract

An air conditioning refrigerating device comprises a high back pressure rotary compressor; an outlet of the high back pressure rotary compressor is connected with an inlet of a condenser; an outlet of the condenser is connected with a liquid inlet of a heat regenerator; the liquid outlet of the heat regenerator is connected with an inlet of a swelling valve; an outlet of the swelling valve is connected with an inlet of an evaporator; an outlet of the evaporator is connected with an air inlet of the heat regenerator; an air outlet of the heat regenerator is connected with an inlet of the high back pressure rotary compressor. According to the air conditioner refrigerating device, refrigerant firstly enters into the high back pressure rotary compressor, enters into the compressor after being compressed into high temperature high pressure air, then is condensed into intermediate temperature high temperature liquid and discharges heat to the air; the refrigerant then flows through the heat regenerator to enter into the swelling valve to be throttled to be in a low temperature low pressure air-liquid mixed state; then the refrigerant enters into the evaporator to change heat with the air in the environment to enable the air temperature to be reduced; accordingly the refrigerating effect is achieved. The air conditioner refrigerating device has the advantages of improving the compressor efficiency and a refrigeration coefficient of a refrigeration system and being good in lubricating oil return.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an air-conditioning and refrigeration device with a regenerator. Background technique [0002] Because CFCs (hydrochlorofluorocarbons) and HCFCs (hydrofluorocarbons) refrigerants have a destructive effect on the ozone layer, the refrigerants commonly used in the field of refrigeration and air conditioning have been eliminated or will be phased out gradually. Now the refrigerants widely used in the field of refrigeration and air conditioning Refrigerants include R134a (freon HFC134a), and HFC mixture refrigerants R404A, R407C, R410A, etc. The molecules of these refrigerants contain hydrogen and fluorine, do not contain chlorine, do not destroy the ozone layer, but have a high greenhouse effect. The trend of global warming is becoming more and more serious, and these alternative refrigerants are also facing the situation of being phased out of the refrigeration field. Hydroc...
