Description
Technical field
The present invention relates to carbon dioxide heat-pump technical field, and in particular to a kind of evaporator external coating, evaporator and its system
Preparation Method.
Background technology
The beginning of the nineties in last century, the Lorentzen professors of NTH universities of Norway propose Trans-critical cycle according to CO2 special physical property
CO2 is circulated, and has greatly promoted CO2 systems in the development of refrigerating field.In the past more than ten years, domestic and international many research aircrafts
Structure has put into substantial amounts of research to transcritical CO_2 circulation, a study hotspot as refrigeration circle.Transcritical CO_2 system is in height
The exothermic process of the larger temperature change (about 80-100 DEG C) of side is pressed, hot water heating is highly suitable for, therefore, heat pump is led
The research in domain starts from Teat pump boiler at first.
Teat pump boiler is general by compressor, gas cooler, evaporator, regenerator, gas-liquid separator, restricting element etc.
Composition.
With inverse Carnot cycle principle, carbon dioxide is done manual work by compressor is changed into the overcritical of HTHP by gaseous state
Heat exchange is carried out with outer circulation working medium such as water in fluid, gas cooler, near critical is changed into after supercritical carbon dioxide heat release
Fluid, the heat of outer circulation water absorption working medium, which progressively heats up, becomes hot water, after the expanded valve throttling of carbon dioxide, is changed into low temperature low
The fluid liquid of pressure, by evaporator absorb surrounding air in heat, this process carbon dioxide heat absorption occur by liquid to
Gaseous phase transformation, is eventually returned to compressor and completes circulation.
In the heat during evaporator absorbs surrounding air, the evaporator of common metal outer wall with the progress of heat exchange, by
It is too low in evaporator outside wall temperature, easily in evaporator outer wall formation ice crystal or ice cube, cause heat exchange efficiency to reduce, and then influence
Operating efficiency to heat pump to evaporator material, it is necessary to be further improved, and on the one hand the lasting progress of guarantee heat absorption, keeps away simultaneously
Exempt to produce ice crystal.
