Description

The high efficiency energy saving refrigeration device

The utility model belongs to refrigerating plant, particularly a kind ofly improves refrigerating efficiency, energy savings, utilizes waste heat to produce the high efficiency energy saving refrigeration device of the refrigeration plant two-stage radiation of hot water.

At present refrigeration plant kinds such as refrigerator, ice box, air-conditioner are more, but condenser distribute has wasted the energy in the fully effectively utilization of failing of the heat in space.Existing energy-saving electric refrigerator, as Chinese patent CN2102480U " using refrigerator " and ZL93247180.3 " energy-saving hot water refrigerator " more, be on the basis of existing refrigerator, to set up cistern device, condenser is immersed in the water the water heating, when water temperature rises to more than 40 ℃, will influence refrigerating efficiency.

The purpose of this utility model provides a kind ofly can make full use of the energy, improve refrigerating efficiency, utilize waste heat to produce hot water, and the refrigerating efficiency high efficiency energy saving refrigeration device that not influenced by water temperature.

The utility model is achieved in that in refrigeration system, one cooling water tank is set between compressor and condenser, the pipeline that the cold-producing medium circulation is installed in cooling water tank submerges, one end of pipeline is connected in the outlet of compressor, the other end is connected with the inlet of condenser, after the cold-producing medium of heat is carried in compressor sucking-off in the freezer evaporator, gaseous refrigerant with cold-producing medium boil down to HTHP, by the pipeline in the cooling water tank time with most of exchange heat to water, cooling liquefaction rapidly, improve water temperature and obtain hot water, the heat of the few portion of residue enters condenser and distributes the space once more.

The utility model has following advantage: in the high efficiency energy saving refrigeration device, high temperature and high pressure gaseous refrigerant from the compressor discharge, at first carry out Forced water cooling but by the pipeline in the cooling water tank, and most of exchange heat to water, residue small part heat enters the condenser cooling of dispelling the heat once more, therefore reduced condenser duty and shortened available machine time of compressor, utilized waste heat to obtain hot water simultaneously, promptly saved the energy and improved refrigerating efficiency again.In addition also owing to the pressure load of doing mutually that has reduced compressor has improved service life and since cold-producing medium by Forced water cooling but the last little heat in back enter the condenser heat radiation again and cool off, so the hot environment adaptability of high efficiency energy saving refrigeration device is strong.

Concrete structure of the present utility model is provided by following examples and accompanying drawing

Fig. 1 is the schematic diagram of high efficiency energy saving refrigeration device.

See accompanying drawing 1, the cold-producing medium of heat is carried in evaporimeter (7) the interior sucking-off of compressor (1) from refrigerating chamber (8), be compressed to high temperature and high pressure gaseous refrigerant, enter pipeline (3) in the cooling water tank (2) most of exchange heat to water, residue small part heat enters condenser (4) liquefaction of lowering the temperature once more, liquid refrigerant is removed moisture through device for drying and filtering (5) then, pass through capillary (6) again and reduce pressure and temperature, enter devaporation heat absorption in the evaporimeter (7) in the refrigerating chamber (8) at last.So just finished sucking-off heat from refrigerating chamber (8), through Forced water cooling but with cool off the energy-efficient circularly cooling process of two-stage radiation combine naturally.

Claims

1. high efficiency energy saving refrigeration device, the high efficiency energy saving refrigeration device that comprises pipeline (3) in cooling water tank (2) in refrigerator, ice box, the air-conditioner refrigerating system and the water tank, pipeline (3) one ends that it is characterized in that being located in the cooling water tank (2) between compressor (1) and the condenser (4) are connected with the outlet of compressor (1), and the other end is connected with the import of condenser (4).
