Abstract
The utility model relates to an anti-frost vapor-liquid separator for a heat pump air-conditioner. The anti-frost vapor-liquid separator has simple structure technology, can increase the internal temperature and pressure so as to improve the suction pressure of a compressor, can ensure an evaporator to work in the evaporation temperature that is slightly higher than the frosting temperature of outdoor air, can effectively avoid the formation of frost layers on the surface of heat exchange fins of the evaporator in winter and enables the system to normally work under the operating condition of low temperature environment. The structure of the utility model is characterized in that heating elements are inserted, wound or applied in the vapor-liquid separator, and the outer surface of the vapor-liquid separator is wound, applied or sheathed with the heating elements, or the heating elements are respectively installed on the outer surface and in the vapor-liquid separator, wherein the heating elements adopt ribbon, wire form, block-shaped, or cylindrical electrothermic components. The anti-frost vapor-liquid separator can be widely suitable for heat pump water heaters (air source water heaters) or heat pump air-conditioners.
Description
Technical field
The utility model belongs to the pipe fitting on the refrigerated air-conditioning system, relates to a kind of vapour liquid separator.
Background technology
The water heater (or claiming air source heat pump) and the heat pump air conditioner that are driven by air-conditioning heat pump all are extensive use of by people, and be popular deeply.This air source hot pump water heater heats or heat pump air conditioner heating, all be with the cold of water or the cold of indoor low temperature air, discharge by off-premises station, and for the water in the water heater or room air provide heat, but all have the defrosting problem on evaporimeter heat exchange fin surface in winter.When the evaporating temperature of operating evaporimeter is lower than the frost layer temperature (the refrigeration technical term claims dew-point temperature) of condensing in the outdoor air, the meeting frosting of evaporimeter heat exchange fin surface, what extensively adopt at present is that the heat pump circulating system medium is carried out hot gas defrosting to outdoor evaporimeter, but reduced the heating load of hot water or room air simultaneously, reduce the thermal efficiency, thereby do not reached the purpose of normal heat supply in winter.The number of patent application of the applicant's application is 200520100105.0, and name is called " evaporimeter that a kind of heat pump is used ".This kind evaporimeter characteristics are, can stop at the surface of evaporimeter heat exchange fin frost layer and form, specific embodiments is, being connected the copper pipe outer surface, exposing the outer surface that is connected copper pipe between the outer surface of the copper pipe elbow of evaporimeter outside and evaporator outlet and heat pump compressor import and all twine or apply ointment or plaster or the suit heater element between restricting element outlet and evaporator.Operability technological process is relatively poor though this patent effect is good, twine apply ointment or plaster or suit heater element area more, the structure more complicated.
The utility model content
The utility model is at the shortcoming of prior art, and a kind of structural manufacturing process is fairly simple, stop that evaporimeter heat exchange fin surface frost layer forms effective, the white type vapour liquid separator of resistance that can provide as a kind of parts separately are provided.
For achieving the above object, the technical scheme of taking:
With on the outer surface of the vapour liquid separator on the pipeline that is installed between evaporator outlet and the compressor inlet and its inside, heater element is set all.
Advantage of the present utility model
Owing to, its temperature inside rising, pressure are increased to this vapour liquid separator heating, promptly improved the pressure of inspiration(Pi) of compressor, evaporimeter is a bit larger tham under the white temperature of coagulating of outdoor air in its evaporating temperature moves.Like this, just, can eliminate the reason of evaporator fin frosting at all.Thereby solved the formation that stops evaporimeter heat exchange fin surface frost layer, made heat pump air conditioner or the Teat pump boiler can normal heat supply under the lower outside air temperature.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Be embodiment of the present utility model as shown in the figure, the vapour liquid separator 2 that is connected between evaporimeter 1 exit and compressor 4 import departments is arranged in the drawings, twine on the outer surface of this vapour liquid separator 2 or apply ointment or plaster or suit heater element 3; Peg graft or the winding or the heater element 3 of applying ointment or plaster in the inside of this vapour liquid separator 2; Or on the inside of vapour liquid separator 2 and outer surface, heater element 3 is installed respectively.Heater element 3 adopts band shape, wire, bulk or columned electrothermal component.
Claims (4)
1, a kind of resistance of heat pump air conditioner frost type vapour liquid separator is installed on the pipeline between evaporimeter (1) outlet and compressor (4) import department, it is characterized in that in the outer surface and the inside of vapour liquid separator (2) heater element being set all.
2, by the resistance frost type vapour liquid separator of the described heat pump air conditioner of claim 1, it is characterized in that on the vapour liquid separator outer surface, twining or applying ointment or plaster or suit heater element (3); Peg graft or winding or the heater element of applying ointment or plaster (3) in the inside of vapour liquid separator (2).
3,, it is characterized in that the inside of vapour liquid separator (2) and outer surface respectively install heater element (3) by the resistance of the described heat pump air conditioner of claim 1 frost type vapour liquid separator.
4, by the resistance frost type vapour liquid separator of the described heat pump air conditioner of claim 1, it is characterized in that heater element (3) adopts band shape, wire, bulk or columned electrothermal component.
