Description
Technical field:
The utility model relates to refrigeration technology field, refers in particular to a kind of cooling-water machine of compression-type refrigeration.
Background technology:
Known cooling-water machine be with freon as refrigerant, by compressor work, refrigerant temperature and pressure after the heat absorption are raise (being higher than environment temperature), at this moment, refrigerant just can be the heat transferred environment; Then, by the throttling step-down, refrigerant is evaporation heat absorption at low temperatures again, i.e. heat in the absorption refrigerating water, thus obtain the chilled water of low temperature, so continuous circularly cooling.Freon is a kind of material of non-environmental protection, too much use can cause atmosphere pollution, influence is ecological, thereby, under the form that environmental requirement is progressively improved along with society, the cooling-water machine of traditional freon refrigeration is not also just advocated and is used, so far develop a kind of cooling-water machine of novel environment friendly, then become the problem that industry is paid close attention to.
The spirit that the applicant is adhering to the research innovation, keeping on improving is utilized its professional eye and professional knowledge, works out a kind of with CO
2Be refrigerant, applied range meets the refrigeration unit of industrial utilization.
The utility model content:
It is a kind of with CO that the purpose of this utility model is to provide
2Be refrigerant, the air-cooled efficient CO of environmental protection, practicality
2Refrigeration unit.
The utility model purpose again provides a kind of structure optimization, and cost is low, the refrigeration unit of good energy-conserving effect.
For achieving the above object, the utility model adopts following technical scheme:
Air-cooled efficient CO
2Refrigeration unit comprises a compressor, a condenser and an evaporimeter; Compressor is realized compression CO
2Form refrigerant; Condenser is docked with the output of compressor, which is provided with the condensation fan of air-cooled usefulness, condenser transport CO
2The pipeline of refrigerant is a total points tactic pattern in a word, and promptly a house steward advances to be divided into many again and is in charge of before this, and then gathers output; Evaporimeter is docked with the output of condenser, and is provided with filter and choke valve on the connecting line between evaporimeter and the condenser, and evaporimeter is incorporated in the water tank, and water tank is provided with chilled water and imports and exports; The delivery outlet of evaporimeter connects compressor.
Described evaporimeter transport CO
2The pipeline of refrigerant is a total points tactic pattern in a word, and promptly a house steward advances to be divided into many again and is in charge of before this, and then gathers output; And gather the house steward caliber of the caliber of output greater than input.
Be compared with the prior art, the utility model is with CO
2As refrigerant, satisfy environment protection requirement, the cold water of thermophilic can be provided, satisfy life or industry utilization, reasonable in design, and optimum organization, cost of manufacture is low, the cost performance height.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the CO that transports of condenser
2The structural representation of the pipeline of refrigerant;
Accompanying drawing 3 is the CO that transports of evaporimeter
2The structural representation of the pipeline of refrigerant.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Air-cooled efficient CO shown in Figure 1, that the utility model provides
2Refrigeration unit comprises a compressor 1, a condenser 2 and an evaporimeter 3.
Evaporimeter 3 is docked with the output of condenser 2, and is provided with filter 4 and choke valve 5 on the connecting line between evaporimeter 3 and the condenser 2, and evaporimeter 3 is incorporated in the water tank 6, and water tank 6 is provided with chilled water and imports and exports 61,62; The delivery outlet of evaporimeter 3 connects compressor 1, reaches periodic duty.Shown in Figure 3, evaporimeter 3 transport CO
2The pipeline of refrigerant is a total points tactic pattern in a word, and promptly a house steward 3a advances to be divided into many again and is in charge of 3b before this, and then gathers output; And the caliber of pipeline 3c that gathers output is greater than the caliber of the house steward 3a of input.This structure can improve heat absorption efficiency, promotes refrigeration, obtains chilled water ideally, and this structure also can be with CO
2The refrigerant step-down is with suitable compressor 1 recompression work.
The utility model course of work is described below:
1), compressor 1 gets electric work with CO
2Be compressed into the refrigerant of high temperature, high pressure, export to condenser 2 then.
2), condensation fan 21 work of the air-cooled usefulness on the condenser 2, the heat of the refrigerant of high temperature, high pressure is passed, realize reducing temperature and pressure, the total points general construction design of condenser 2 internal duct, can satisfy the requirement of cooling, step-down, the refrigerant that obtains preference temperature and pressure is exported to evaporimeter 3.
3), refrigerant is defeated by before the evaporimeter 3, through filter 4 and choke valve 5 effects, filter and regulate flow, further throttling step-down, refrigerant enters evaporimeter 3 evaporation heat absorption at low temperatures again then, promptly absorb the heat of chilled water in the water tank 6, thereby the chilled water that acquisition is wanted is used for life or industry use.
4), the high temperature of evaporimeter 3 outputs, the refrigerant of low pressure then enter in the compressor 1 circularly cooling like this.
The utility model adopts air-cooled, and does design rationally on the pipeline of condenser 2 and evaporimeter 3, reaches and utilizes CO
2Freeze as refrigerant,, satisfy environment protection requirement, the cold water of thermophilic can be provided, satisfy life or industry utilization to substitute the freon of traditional non-environmental protection, reasonable in design, and optimum organization, cost of manufacture is low, the cost performance height.More than diagram is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so every principle according to the utility model is done the equivalence variation or modified, and all should be covered by in the protection domain of the present utility model.
