Description
Technical field:
The utility model relates to a kind of Novel heat pump especially high temperature heat pump compressor oil cooler, belongs to heat pump compressor field and raises the efficiency a kind of new device with reliability.
Background technique:
In refrigeration (heat) system, the effect that compressor plays " heart ", sucks the low temperature low pressure gas in vaporizer and after being compressed into high temperature and high pressure gas, is transported in condenser; Lubricant oil is then compressor " blood ", carries out lubrication and cooling to the bearing in compressor, and in addition, for dissimilar compressor, lubricant oil also plays provides other effect such as power, sealing.
The lubricant passage way system of compressor, is generally made up of oil pump, oil cooler, oil strainer etc.Lubricant oil, through oil pump, supplies each bearing of compressor, lubricates it after boost in pressure, and takes away the heat that revolute pair produces, and the lubricant oil after intensification enters oil cooler, returns the circulation that compressor oil-supplying pipe-line system completes lubricant oil after supercooling.
The type of cooling of oil cooler generally adopts traditional working medium cooling or water cooling two kinds.Traditional working medium type of cooling, is draw refrigeration agent from system condenser, enters oil cooler, cool lubricant oil after throttling.For heat pump especially high temperature heat pump compressor, along with the raising of system condensing temperature, by the impact of refrigerant property, refrigerating capacity after refrigeration agent throttling can be deteriorated, and heat transfer temperature difference also can be more and more less, and cause the cooling effect of oil cooler significantly reduce and finally aggravate the damage of bearing, can not meet the cooling capacity of oil cooler even at all and cause compressor out of service because oil temperature continues to rise; Although traditional water cooling mode is not by the restriction of system application operating mode; but along with the growth of system operation time; the water side meeting scaling of oil cooler; thus reduce heat transfer and cooling effect gradually; and for heat pump especially high temperature heat pump compressor; along with the raising of system condensing temperature; oil cooler load increases; in oil cooler, the mean temperature of water can raise; the fouling of this meeting exacerbate water side, sharply reduces the cooling effect of oil cooler, is the impact that reduction incrustation scale causes; regularly must shut down and scale removal, add the maintenance cost of system.
Model utility content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of cooling effect improving heat pump especially high temperature heat pump compressor lubricant oil, extend its bearing working life, reduce operation and maintenance expense, improve the stability of system cloud gray model and the heat pump compressor oil cooler of reliability.
The purpose of this utility model can be reached by following measure: a kind of heat pump compressor oil cooler, it comprises cylindrical shell, the left and right sides of cylindrical shell is respectively equipped with left tube sheet and right tube plate, it is characterized in that cylindrical shell is provided with feed pipe, steam outlet pipe, air vent and sewage draining exit, the left side of left tube sheet is provided with left grease chamber, left grease chamber is provided with air vent and blowdown fuel outlet, heat exchanging tube and liquid separatnig plate is provided with between left tube sheet and right tube plate in cylindrical shell, the right side of right tube plate is provided with right grease chamber, top and lower right grease chamber, right grease chamber, top is provided with oil outlet, air vent, lower right grease chamber is provided with filler opening, blowdown fuel outlet, heat exchanging tube respectively with left grease chamber, right grease chamber, top and lower right grease chamber communicate.
In order to realize the purpose of this utility model further, described feed pipe and flooded evaporator connect, and the connection mouth of feed pipe and flooded evaporator is positioned at below the minimum level of flooded evaporator, described steam outlet pipe and flooded evaporator connect, and the connection mouth of feed pipe and flooded evaporator is positioned at more than the most high liquid level (HLL) of flooded evaporator.
The utility model can produce following good effect compared with the prior art: the utility model utilizes the refrigerant liquid coming from flooded evaporator as cooling medium, the lubricant oil of compressor is cooled, even if under the condensing temperature operating mode that high temperature heat pump system is high (such as 70 DEG C and more than), now the evaporating temperature of system also can lower than or close to the condensing temperature (40 DEG C) of traditional air-conditioning system, therefore, in oil cooler, the cooling capacity of liquid refrigerant is also better than or close to the traditional working medium cold oil cooler of air-conditioning system, improve the cooling effect of heat pump especially high temperature heat pump compressor lubricant oil, improve the operating conditions of each bearing of compressor, extend its working life, make full use of the heat of compressor lubricant oil, improve the heating efficiency of system, eliminate water to oil cooler to need regularly to shut down the trouble to the scale removal of Qi Shui side and expense, improve stability and the reliability of system cloud gray model.
