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 efficient CO of water-cooled 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:

The efficient CO of water-cooled 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 cooling water recirculation system of the usefulness of water-cooled; Condenser contains the CO that transports of a plurality of parallel connections ₂The pipe-line cell of refrigerant, cooling water a plurality of pipe-line cell of flowing through successively; 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 condenser transport CO ₂The pipe-line cell 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.

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 pipe-line cell 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:

Shown in Figure 1, the efficient CO of the water-cooled that the utility model provides ₂Refrigeration unit comprises a compressor 1, a condenser 2 and an evaporimeter 3.

Compressor 1 can realize compressing CO ₂Form refrigerant, this compressor 1 is with commercial acquisition.

Condenser 2 is docked with the output of compressor 1, which is provided with the cooling water recirculation system of the usefulness of water-cooled; Condenser contains the CO that transports of a plurality of parallel connections ₂The pipe-line cell 21 of refrigerant, cooling water a plurality of pipe-line cell 21 of flowing through successively; Shown in Figure 2, condenser 2 transport CO ₂The pipe-line cell 21 of refrigerant is a total points tactic pattern in a word, and promptly a house steward 21a advances to be divided into many again and is in charge of 21b before this, and then gathers output; This pipe-line cell 21 has one-level to be in charge of or multistage being in charge of, every grade to be in charge of number identical or different, and the caliber of input house steward's caliber and delivery trunk can be identical or different.Be in charge of 21b for many and can strengthen heat exchange area, efficient is higher, makes CO ₂Refrigerant fast cooling, step-down promote unit work.
