Detailed description of the invention
Fig. 1 is the structural schematic diagram of the cabinet type air-cooler of hot gas defrosting internal-circulation type of the utility model；
Fig. 2 is the control principle drawing of the cabinet type air-cooler of hot gas defrosting internal-circulation type of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the cabinet type air-cooler of hot gas defrosting internal-circulation type of the utility model includes shell 5, the shell
There are air inlet 1 and air outlet 4 on 5 side wall, has circulating fan 3 in the shell 5 between air inlet 1 and air outlet 4.The air inlet
There is evaporation coil 2 in 1 corresponding shell 5, has first interface and second interface on evaporation coil 2.Feed liquor on 5 side wall of shell
Pipe 8, escape pipe 7 and defrosing pipe 6, one end of inlet tube 8, escape pipe 7 and defrosing pipe 6 is respectively positioned in shell 5, the other end is respectively positioned on
Outside shell 5.Liquid supply electromagnetic valve 9 and swollen is disposed with from its overhanging end to the other end on that section of inlet tube 8 in shell 5
Swollen valve 11 is parallel with the first communicating pipe 13 and between 8 one end of inlet tube in shell 5 and the first interface of evaporation coil 2
Two communicating pipes 16, from inlet tube 8 to being disposed with draining solenoid valve 14, throttling hair evaporation coil 2 on the first communicating pipe 13
Tubule 15, liquid reservoir 17 and check valve 18, the flow direction of check valve 18 are from evaporation coil 2 to liquid reservoir 17.In shell 5
Escape pipe 7 and 6 one end of defrosing pipe are connected with the second interface of evaporation coil 2, and have return-air solenoid valve 12 on escape pipe 7, melt
There is defrosting solenoid valve 10 on white pipe 6.
Wherein, the circulating fan 3 is located at the top of evaporation coil 2.
The evaporation coil 2 is located at the top of liquid reservoir 17.
The lower part and top of 5 one side wall of shell are evenly equipped with stomata, so that the upper and lower part of the shell 5 of shell 5
In grid-like, it is located at air inlet 1 described in those of 5 lower sidewall of shell stomatal limiting value, is located at those of 5 side wall upper part of shell
Air outlet 4 described in stomatal limiting value.
In use, the cabinet type air-cooler is installed in freezer.
When normal refrigeration work: defrosting solenoid valve 10 is closed, and liquid supply electromagnetic valve 94, return-air solenoid valve 126 are opened, work of freezing
Matter successively after liquid supply electromagnetic valve 9, expansion valve 11, the first communicating pipe 13, evaporation coil 2, is passed through from inlet tube 8 from escape pipe 7
The discharge of return-air solenoid valve 12 is crossed, is freezed when refrigeration working medium passes through evaporation coil 2, meanwhile, start circulating fan 3, freezer
Interior gas successively passes through air inlet, evaporation coil 2 and gas outlet, and heat is completed in gas and 2 contact process of evaporation coil and is handed over
It changes, freezes.
When defrosting works: circulating fan 3 shuts down, and liquid supply electromagnetic valve 9, return-air solenoid valve 12 and draining solenoid valve 14 close
It closes, defrosting solenoid valve 10 is opened, and the hot gas that refrigerant is formed enters evaporation coil 2 by defrosting solenoid valve 10, due to evaporating pan
2 temperature of pipe is lower, and hot gas is condensed into liquid when passing through evaporation coil 2, is stored in bottom liquid reservoir 17 after check valve 18.
After defrosting terminates, do not need such as to freeze, due to having set check valve 18 and draining solenoid valve 14 before and after liquid reservoir 17
(closed state), the liquid in liquid reservoir 17 will not cause in liquid reflux to coil pipe because coil temperature reduces, if needed at this time
Freeze, liquid supply electromagnetic valve 9 and return-air solenoid valve 12, which are opened, at this time enters normal refrigeration work, while draining solenoid valve 14 is also beaten
It opens, for liquid reservoir 17 since pressure is higher, refrigerant liquid first passes through 15 reducing pressure by regulating flow of throttle capillary tube, then passes through draining solenoid valve
14 and expansion valve 11 throttle after, enter endothermic gasification in evaporator, realize recycling for refrigerant, until in liquid reservoir 17
Until pressure and 2 pressure of evaporation coil reach balance.
