As shown from the above technical solution, the utility model mainly is to utilize carbon dioxide low temperature storage tank pressure inside, carbon dioxide liquid is pressed into evaporimeter carries out sweat cooling, directly enters in the atmosphere after the cold-producing medium heat absorption.Provide the refrigeration of corresponding time according to the storage capacity of carbon dioxide low temperature storage tank, be implemented in the refrigeration when driving without any extrinsic motive, promptly this system can guarantee the operate as normal of refrigeration system when power scatters and disappears.
Description of drawings
Fig. 1 is a systematic schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
The self-driven refrigeration system of carbon dioxide liquid evacuator body as shown in Figure 1, be connected in sequence by pipeline by carbon dioxide low temperature storage tank 10, needle-valve 20, evaporimeter 30, blower fan 40, capillary 50, heat exchanger 60, check valve 70, stop valve 80, carbon dioxide low temperature storage tank 10 is provided with safety valve 11, bleeder valve 12 and ball valve 13, the output of carbon dioxide low temperature storage tank 10 is communicated with the input of ball valve 13, and the output of ball valve 13 links to each other with the input of needle-valve 20.
As preferred version of the present utility model, between the input of the output of ball valve 13 and needle-valve 20, be provided with first liquid-sighting glass 90 and first thermometer 100, on carbon dioxide storage tank 10, also be provided with first Pressure gauge 14, can conveniently grasp the internal state of carbon dioxide low temperature storage tank 10 by first liquid-sighting glass 90, first thermometer 100 and first Pressure gauge 14 are set.
As preferred version of the present utility model, between the input of the output of evaporimeter 30 and blower fan 40, be provided with second Pressure gauge 110, second thermometer 120 and second liquid-sighting glass 130, by being set, second Pressure gauge 110, second thermometer 120 and second liquid-sighting glass 130 can carry out deep observation to system, control refrigeration system better, guarantee the operate as normal of system.As complete refrigeration system, the part instrument can be matched, and does not influence the operate as normal of refrigeration system.
As preferred version of the present utility model, between the input of the output of heat exchanger 60 and check valve 70, be provided with the 3rd Pressure gauge 140 and the 3rd thermometer 150, observe by the 3rd Pressure gauge 140 and the 3rd thermometer 150 gaseous state after can heat exchanging is set, also can consider after heat exchange, to install flowmeter so that grasp the flow of cold-producing medium in real time.
As preferred version of the present utility model, also can be with through the driving force of the carbon dioxide behind the heat exchanger 60 as blower fan 40.
In this refrigeration system, carbon dioxide low temperature storage tank 10 is core components, need to adopt vacuum insulation to handle, and at present, carbon dioxide low temperature storage tank is applicable to the storage capacity greater than 1 ton, and refrigerating capacity is greater than 1KW, and the duration was greater than 36 hours environment; Also can adopt the Dewar jar of low capacity, it is applicable to the storage capacity less than 1 ton, and refrigerating capacity is less than 2KW, and the duration was less than 10 hours environment.As preferred version of the present utility model, carbon dioxide low temperature storage tank 10 must be furnished with safety valve 11, bleeder valve 12 and ball valve 13, and wherein the safe pressure of safety valve 11 is preferably 30-40bar.
