Abstract

The utility model relates to a cold air conditioner which comprises a compressor, a condenser, a drying tank, an auxiliary condensing tube, an expansion valve and an evaporator. The compressor drives gaseous refrigerant into the upper part of the condenser through a sealed pipeline; the refrigerant flowing through the condenser turns into the liquid state from the gaseous state; the liquid refrigerant flowing out from the lower part of the condenser passes through the drying tank and firstly are cooled for the second time by the auxiliary condensing tube arranged under the evaporator, and then goes into the expansion valve and finally flows to the evaporator after being throttled and reduced in pressure; the liquid refrigerant passes through the evaporator to be turned into the gaseous state to flow out, and then the gaseous refrigerant is sucked into the interior of the compressor to be supplied to the condenser for turning the gaseous refrigerants into the liquid state to be circulated, therefore, the efficiency of the cold air conditioner is increased.

Description

The cold air conditioner device

Technical field

The utility model relates to a kind of cold air conditioner device, relate in particular to a kind of by with cold-producing medium earlier via after the secondary condenser pipe secondary cooling of being located at the evaporimeter below, enter expansion valve again, and then promote the cold air conditioner device of the efficient of cold air conditioner device.

Background technology

The cold air conditioner device is that Hyundai Motor and building are equipped with substantially, and good heat pump performance can increase user's comfortableness.

The cold air conditioner device is to use the circulatory system, refrigerant (R134a or R12) is constantly carried out the conversion of liquid and gaseous state situation.

Automobile-used or the building of prior art cold air conditioner principle and indifference, with as Fig. 4 to prior art bus vertical type thermantidote shown in Figure 7 be example, after automobile engine 80 starts, before air-conditioning is not started working, cold-producing medium in the air-conditioning system is in not recurrent state, intrasystem cold-producing medium is in gaseous state, pressure everywhere equates, temperature is equivalent to outside air temperature, when opening air-conditioning switch, air conditioning clutch is started working simultaneously in conjunction with the electronic fan of automobile, rotates (as shown in Figure 5) because air conditioning clutch binding engine 80 drives compressor of air conditioner 70, and compressor 70 sucks compressor 70 inside with the gaseous refrigerant in the evaporimeter 74, cause evaporimeter 74 internal pressures to reduce, under compressor 70 effects, the increased pressure of cold-producing medium, simultaneous temperature improves, after compressor 70 work, cause no longer balance of air-conditioning system inner refrigerant pressure, this pressure differential is kept the power that system's inner refrigerant circulates exactly.

The cold-producing medium of HTHP enters the top of condenser 70 by the pipeline of sealing, because when electronic fan effect and running car, the leave heat of condenser 71 of flow air is because the cold-producing medium on effect condenser 71 tops of cooling has become the HTHP liquid state by gaseous state.

The liquid refrigerant that flow out condenser 71 bottoms enters drying chamber 72 by the road, and the drier in the drying chamber can be removed the moisture in the cold-producing medium and filter the interior impurity of cold-producing medium.

Pure liquid refrigerant is by the road with than pressure stable and flux and flow direction expansion valve 73, in whole system, expansion valve is the office that control refrigerant enters evaporimeter, and refrigerant enters evaporimeter, and cold air can be not enough very little with regard to being difficult for evaporation too much, so expansion valve is the adjusting maincenter.Flow to evaporimeter 74 at last through throttling and step-down, the inlet of evaporimeter 74 has dwindled the aperture of pipeline.Liquid refrigerant is owing to the low pressure in aperture and the evaporimeter 74, and afterwards moment has become gaseous state by liquid state from the aperture ejection.

Qi Hua process has just absorbed a large amount of heats from the external world like this, evaporimeter 74 surface temperatures become very low, just as ice cube, the air blast of evaporimeter 74 1 sides blows to the ice-cold evaporimeter 74 in surface with air, air themperature through evaporimeter 74 surfaces reduces, cool air just can blow out from the diverse location in the compartment like this, thereby allows the user feel comfortably cool.

Gaseous refrigerant after the expansion is inhaled into compressor of air conditioner 70 again, constantly repeats said process.Air-conditioning system is constantly continuous operation just.

Though condenser 71 and evaporimeter 74 titles are different, but structure is similar, all be a row curved around pipeline on be covered with the sheet metal of heat transmission, realize the device of the heat exchange of material in outside air and the pipeline with this, the condensation of condenser 71 refers to refrigerant loses heat in its pipeline from the gaseous state liquid state of congealing into, evaporimeter 74 is just in time opposite with condenser 71, and it is that cold-producing medium becomes the place that gaseous state (i.e. evaporation) absorbs heat by liquid state.

But the shortcoming of the cold air conditioner device of above-described prior art is cold-producing medium circulation be one unidirectional, single-circuit cyclic process, generally speaking, refrigerant loses heat in condenser 71 pipelines is from the gaseous state liquid state of congealing into, but because of condenser 71 heat radiations can't be complete, so the liquid refrigerant temperature that flows out via condenser 71 belows still can reach about 40 degrees centigrade high temperature, and then make and follow-uply flow to evaporimeter 74 cold-producing mediums via expansion valve 73 throttlings and step-down and can't bring into play the low pressure gasifying of adjusting effect should be arranged, can influence the usefulness that evaporimeter 74 absorbs heat, so, will help the cold air efficiency of cold air conditioner device if can reduce once more by the liquid temperature of the cold-producing medium that flow out condenser 71 belows.

The utility model content
