Abstract
The utility model relates to a modular air-cooling cold and hot water unit which is characterized in that a four-way valve is connected with a compressor, a heat exchanger, and a fin heat exchanger; a economizer is connected with the heat exchanger and an expansion valve; the expansion valve is connected with the fin heat exchanger and a liquid-vapor separator; the liquid-vapor separator is connected with the compressor; one connecting tube is led out from a connecting tube between the expansion valve and the fin heat exchanger and is connected to the economizer through a left solenoid valve and then to the liquid-vapor separator; a balance tank is disposed in the middle of a connecting tube between the heat exchanger and the economizer; and a heating pipe is led out from the middle part of a connecting tube between an exhaust port of the compressor and the four-way valve and is connected with the liquid-vapor separator through a solenoid valve. The modular air-cooling cold and hot water unit solves the problems that liquid return may occur during low-temperature heating and the heating capability of a system cannot be fully utilized because of insufficient refrigerant. Compared with a conventional air-cooling cold and hot water unit, the modular air-cooling cold and hot water unit is characterized by greater charging quantity of the refrigerant, greater heating capacity, higher efficiency, lower operation cost, no liquid return, and higher stability.
Description
Technical field
The utility model relates to Air cooler, particularly a kind of modular wind cooling cold and hot water unit.
Background technology
Before the utility model invention, in the wind cooling cold and hot water unit, adopt compensator to replace fluid reservoir at present.There is a limitation in this design; Promptly when heating,, compensator can not change the storage capacity of refrigerant along with the variation of operating mode owing to can only storing quantitative refrigerant; Especially when low-temperature heating, the refrigerant demand causes back the liquid phenomenon easily than next low of standard condition; Simultaneously; This design is in order to yield to the limitation of compensator; Be that refrigerant demand with worst cold case decides system's coolant charging amount when considering the coolant injection amount, thereby cause system when standard condition, can not bring into play the due heating capacity of system because of cold medium shortage.
Summary of the invention
The purpose of the utility model just is to overcome above-mentioned defective, designs a kind of modular wind cooling cold and hot water unit.
The technical scheme of the utility model is:
Modular wind cooling cold and hot water unit; Its major technique is characterised in that compressor is connected with the D interface of cross valve; C interface through cross valve is connected with heat exchanger; The heat exchanger other end is connected with the E interface of economizer, and the F interface of economizer is connected with expansion valve one end, and the other end of expansion valve is connected with finned heat exchanger; The other end of finned heat exchanger is connected with the A interface of cross valve after the B interface of cross valve is connected with the K interface of gas-liquid separator; The L interface of gas-liquid separator is connected with the air entry of compressor again, between the tube connector of expansion valve and finned heat exchanger, draws the G interface of another root tube connector through left magnetic valve to economizer, and the H interface by economizer is connected with the M interface of gas-liquid separator again; Compensator is installed in the middle of the tube connector of the E interface of heat exchanger and economizer, draws a heating pipe at the exhaust outlet of compressor with the tube connector centre of the D interface of cross valve and be connected with the N interface of gas-liquid separator through magnetic valve.
The advantage of the utility model is bigger than existing product coolant injection amount; Make at the heating capacity of metric system thermal condition bigger, higher in the efficient of metric system thermal condition, make operating cost reduce; When the low-temperature heating operating mode, do not return liquid, improve the stability of unit greatly.
Other advantage of the utility model and effect will continue explanation below.
Description of drawings
The system schematic of Fig. 1---the utility model.
The corresponding expression of each label parts are following among the figure:
Compressor 1 (comprising exhaust outlet and air entry), cross valve 2 (A ,-B ,-C ,-D), heat exchanger 3, compensator 4, economizer 5 (E ,-F ,-G ,-H), expansion valve 6, left magnetic valve 7, finned heat exchanger 8, gas-liquid separator 9 (K ,-L ,-M ,-N), heating pipe 10, magnetic valve 11.
The specific embodiment
As shown in Figure 1:
The structure explanation of the utility model:
The application note of the utility model:
As shown in Figure 1; System is heating in the circulation; Gaseous coolant is discharged after compressor 1 is compressed to high temperature and high pressure gas and is got into cross valve 2-D interface; Get into heat exchanger 3 through cross valve 2-C interface again, high temperature and high pressure gas gets in the economizer 5 through economizer 5-E interface behind the liquid refrigerants of heat exchanger 3 li heat release coolings becoming HTHP, gets into expansion valve 6 by economizer 5-F interface again; The liquid refrigerant of HTHP becomes the liquid refrigerants of low-temp low-pressure through becoming the liquid refrigerants of low-temp low-pressure behind the expansion valve 6 when standard condition; Because system's refrigerant circulation when refrigeration is more than what heat; Compensator 4 can store the certain amount of fluid refrigerant, and remaining liquid coolant will directly get into finned heat exchanger 8 heat absorptions and flash to gaseous coolant again through getting back to the next circulation of compressor 1 beginning behind the cross valve 2 entering gas-liquid separators 9.
When worst cold case; Because participating in the refrigerant of circulation lacks than standard condition; Add compensator 4 and stored full refrigerant, can not store this unnecessary liquid refrigerants again, at this moment left magnetic valve 7 will be opened; The liquid refrigerants branch of part low-temp low-pressure flowed into directly get into vapour liquid separator 9 after heat of vaporization that economizer 5 draws the liquid refrigerants of HTHPs becomes gas, avoid excessive liquid refrigerants to get back to compressor and cause liquid hammer.When the low temperature bad working environments; Magnetic valve 11 will be opened; The gas of part HTHP is directly introduced gas-liquid separator further give excessive liquid refrigerants heating and gasifying, guarantee that not having excessive liquid coolant to get back to compressor causes liquid hammer, guarantees the stable operation of security of system.
