Technical field
The utility model relates to a kind of commercial refrigerator.
Background technology
At present, commercial refrigerator is carried out with the heat of refrigerator inside by the heat pump type refrigerating system in process of refrigerastion, by the air blast cooling finned cooler or naturally cooling wire type condenser heat is discharged, the heat that is discharged from raises the temperature around the refrigerator, worsened to a certain extent environment, not only wasted energy and also people's life has been caused bad impact.
Summary of the invention
For the lower deficiency of used heat, efficiency of the environment that exerts an influence that overcomes existing commercial refrigerator, the utility model provides a kind of higher energy-saving commercial refrigerator of used heat, efficiency of the environment of effectively avoiding exerting an influence.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of energy-saving commercial refrigerator comprises refrigeration or refrigerating chamber, compressor, condenser, condensation fan, thermorelay, device for drying and filtering, capillary and evaporimeter; Described evaporimeter is positioned at described refrigeration or refrigerating chamber, the refrigerant inlet of described evaporimeter is connected with capillary, described capillary is connected with device for drying and filtering, described device for drying and filtering is connected with the refrigerant outlet of condenser, described condensation fan is positioned at the condenser side, the refrigerant inlet of described condenser is communicated with the refrigerant outlet of compressor, install in order to the thermorelay according to the start and stop of refrigerant temperature size control condensation fan at the refrigerant inlet place of described condenser, the refrigerant inlet of described compressor is communicated with the refrigerant outlet of described evaporimeter, described commercial refrigerator also comprises the heat exchange bucket, described heat exchange bucket comprises shell, heat exchanger tube and in order to hold the metal inner core of water to be heated, described heat exchanger tube is coiled on the described metal inner core, described heat exchanger tube and described metal content outer wall close contact, the refrigerant outlet of described compressor is connected with the import of described heat exchanger tube, and the outlet of described heat exchanger tube is connected with the refrigerant inlet of described condenser.
Further, be provided with heat-insulation layer between described metal content and the shell.
Described evaporimeter is finned or pipe-coil type evaporator, and described condenser is finned or coiled tube condenser.
Technical conceive of the present utility model is: install the heat exchange bucket with heat insulation function before the condenser of commercial refrigeration system of refrigerator additional, the heat exchange bucket can cool off the refrigeration working medium of the HTHP that compressor in the refrigerator refrigeration system discharges before condenser, with this heat with storage barrel in domestic water; Increase a thermorelay in the refrigeration working medium exit of bucket in order to control the start and stop of air blast cooling finned cooler blower fan, under the prerequisite that guarantees condensation effect, reduce the energy consumption of blower fan.
The beneficial effects of the utility model are mainly manifested in: the used heat that the refrigerator that utilizes original technology to produce by the heat exchange bucket produces in process of refrigerastion, heat domestic water, and eliminated the harmful effect that used heat increases life cycle, obtained simultaneously useful hot water.
Cool off by the refrigeration working medium of heat exchange bucket to the HTHP of compressor discharge, reduced Condenser duty, can reduce the energy consumption of refrigerator or the material cost of reduction refrigerator.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1～Fig. 4, a kind of energy-saving commercial refrigerator comprises refrigeration or refrigerating chamber 1, compressor 2, condenser 3, condensation fan 4, thermorelay 5, device for drying and filtering 6, capillary 7, heat exchange bucket 8 and evaporimeter 13;
Wherein, heat exchange bucket 8 is comprised of bucket 11 and shell 12 in heat exchanger tube 9, insulation material 10, the metal, heat exchanger tube 9 be coiled in the metal on the bucket 11 with metal in bucket 11 close contacts have good heat conductivility, in metal, filling insulation material 10 between bucket and the shell 12.
Wherein evaporimeter 13 can be finned also can be coiled.
Wherein condenser 3 can be finned also can be coiled.
Discharged as shown in Figure 4 the cold-producing medium of HTHP during refrigerator work by compressor 1, cold-producing medium flows through heat exchanger tube 9 on the heat exchange bucket 8 along pipeline, bucket 11 is with the water in the heat transferred heat exchange bucket 8 of high-temperature high-pressure refrigerant in heat exchanger tube 9 and the metal, make the temperature rising of water obtain the hot water that we need, this moment, refrigerant temperature also decreased, cold-producing medium after temperature reduces flows to condenser 3 along refrigeration pipe again, if thermorelay 5 records heat exchange bucket 8 exit excess Temperatures, then control condensation fan 4 work, cold-producing mediums in the condenser 3 are condensed, and wind that blower fan 4 blows out is forced cooling, 8 exit temperature are not high if thermorelay records the heat exchange bucket, then controlling condensation fan 4 stops, thereby reduce the consumption of refrigerator electric energy, temperature reduces after the cooling of cold-producing medium process heat exchange bucket 8 and condenser 3, but also keep high pressure conditions, cold-producing medium occured to become liquid phase transformation by steam state after temperature reduced under high pressure conditions, cold-producing medium is discharged a large amount of heats in phase transition process, and heat is absorbed by the water in the heat exchange bucket 8 and condenser 3 ambient airs, liquid refrigerant continues to flow in the evaporimeter 13 through device for drying and filtering 6 and capillary 7, because the throttling action of capillary 7 has reduced rapidly the pressure of cold-producing medium in evaporimeter 13, pressure decreased is so that cold-producing medium becomes steam state by liquid state, cold-producing medium has absorbed a large amount of heat in refrigerator cold-storage or the refrigerating chamber 1 interior air by evaporimeter 13 during phase transformation again, temperature in refrigerator cold-storage or the refrigerating chamber 1 is reduced, the cold-producing medium that becomes mutually gas in evaporimeter 13 is sucked by compressor 1 again and compresses, become the gas of HTHP after the compressed acting, discharge compressor 1 and enter heat exchange bucket 8, so circulation, water in the heat exchange bucket 8 is constantly heated up, the air in refrigerator cold-storage or the refrigerating chamber 1 is constantly lowered the temperature.
