A radiation heat dissipation and radiation heat collection-based cold and hot central air conditioning system includes a compressor, a liquid storage device, an indoor unit and an outdoor unit connected in sequence, the outdoor unit includes a radiation heat collector; the radiation heat collector includes a protective plate, a heat absorption plate, and a plate core; the heat absorption plate is located between the plate core and the protective plate; the plate core comprises a heat exchange medium inlet end and a heat exchange medium outlet end; and the heat absorption plate is used for transferring absorbed heat to a heat exchange medium circulating in the plate core. The heat absorption plate collects heat, and then transfers the heat to the heat exchange medium flowing in the plate core; and the heat exchange medium carrying the heat is compressed by the compressor, and then enters the indoor unit for heat exchange.

Radiation heat dissipation and radiation heat collection-based cold and hot central air conditioning system

A single-stage carbon dioxide multi-split cooling and heating multifunctional central air conditioner, comprising a single-stage carbon dioxide circulation system using carbon dioxide as a circulation working medium; the single-stage carbon dioxide circulation system comprises an outdoor unit and a plurality of end heat exchangers provided in parallel; and the carbon dioxide medium performs cooling and/or heating in a circulating manner in a carbon dioxide compressor, an outdoor heat exchanger, a liquid storage tank and the end heat exchangers which are in communication with one another.

A carbon dioxide refrigerating system and a refrigerating method thereof. A carbon dioxide refrigerating system, comprising a compressor, a condenser, a liquid storage device, and an evaporator connected in sequence; a suction assembly is arranged between the compressor and the condenser, the suction assembly being in communication with the liquid storage device and in communication with a gas-liquid separator, the gas-liquid separator being arranged between the condenser and the liquid storage device, and the carbon dioxide gas in the liquid storage device or the gas-liquid separator being capable of being sucked back into the pipeline between the compressor and the condenser by means of the suction assembly.

Carbon dioxide refrigerating system and refrigerating method thereof

Disclosed is a flash closed heat exchanger, comprising a closed housing. A negative pressure fan is provided on the closed housing. A negative pressure environment is formed inside the closed housing by means of the negative pressure fan. A water atomization device is provided inside the closed housing. The water atomization device sprays atomized water into the inside of the closed housing, so that the atomized water evaporates into steam in the negative pressure environment. In the flash closed heat exchanger, the evaporation of atomized water is promoted in a closed negative pressure environment.
