Description
Technical field
The utility model relates to power saving refrigerator equipment, especially a kind of novel energy-conserving freezer that can Extra Supply hot water.
Background technology
The most mechanical freezers of China mainly are to adopt the steam compression type refrigeration mode to regulate the storehouse temperature at present, and its refrigeration principle is the evaporation that utilizes the lower liquid refrigerant of vapourizing temperature, and the heat that absorbs in the storage environment descends the storehouse temperature.Cold-producing medium after will vaporizing by compressor sucks back and pressurizes, and cold-producing medium is with the heat transferred cooling medium that absorbs in condenser, and self temperature reduces and is condensed into liquid again, and then evaporates heat absorption, and so circulation realizes continuous cooling.
Refrigeration system comprises 4 major parts: compressor, condenser, expansion valve (choke valve), evaporimeter.Whole refrigeration system is connected by circulation line, constitutes an airtight loop.Fill cold-producing medium in the pipeline.
Compressor plays a part compression and refrigerant conveying gas in refrigeration system, promptly the low-pressure low-temperature gas that produces in the evaporimeter is sucked back, and is collapsed into high temperature and high pressure gas once more and sends into condenser.
Condenser is used for the high temperature and high pressure gas that compressor is pressed into is cooled off and condensation, under certain pressure and temperature, the gas liquefaction of HTHP is become normal temperature high voltage liquid.
Expansion valve is installed between liquid reservoir and the evaporimeter, is a separation of system inner high voltage district and low-pressure area, and its effect is that highly pressurized liquid throttling is expanded, and becomes low pressure liquid, and it also is the outpost of the tax office of regulating and control refrigerant flow.
In evaporimeter, the low pressure refrigerant after the throttling expansion absorbs heat and is evaporated to gas from storehouse, makes the storehouse temperature drop low, reaches the purpose of refrigeration.
Compressor plays action of the heart in whole refrigeration system, provide the process of energy compensating.Condenser and evaporimeter are two heat exchangers, and the former makes the gas heat release of high-pressure refrigerant, and is converted into liquid; The latter makes the liquid heat absorption of low pressure refrigerant, and is converted into gas.Cold-producing medium becomes the delivery vehicle of heat energy in the process of moving in circles.
The applicant finds present refrigeration plant in being engaged in design, installation, construction, the work of debugging freezer equipment for many years, no matter be central air conditioning equipment, still the utilization rate of large, medium and small type freezer equipment is lower.Refrigeration plant is in when operation, and consumed power produces two kinds of energy, a kind of be exactly cold energy source, another kind be exactly heat energy, and people have just utilized the cold energy source at present, and the heat energy of equipment generation almost all directly is emitted in the air, is not used effectively.Refrigeration plant is when operation, and the heat energy that is produced is than cold energy source about 20%.The waste of this heat is serious, is exactly in heat release as large-scale refrigeration plant central air-conditioning roof cooling tower, as long as compressor work produces cold, the heat or the more heats that just have as much are discharged in the air.
On the other hand, at present for the freezer engineering, the power consumption of electricity defrosting in refrigeration plant accounts for 2/5 of the total power consumption of equipment.Not only defrosting time is long, to remove in clean but also the storehouse rise temperature difference big to use extra defroster, the secondary long operational time, and electricity defrosting accident rate height, accident potential exists always, and refrigeration industry and user are difficult to solution.

The specific embodiment
Following embodiment illustrates novel energy-conserving freezer of the present utility model in conjunction with the accompanying drawings without limitation.Those skilled in the art; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification, so all equivalent technical schemes also belong to category of the present utility model, its scope of patent protection is limited by the application's claims.
As shown in Figure 1, for JG-05T type freezer, 3.75KW compressor 2 (acting), condenser 3 (heat release), expansion valve 4 (choke valve) and evaporimeter 1 (heat absorption) are arranged in shell, this four big part couples together it and forms a complete closed cycle system, and working medium (also being refrigerant) is arranged in this circulatory system.This freezer heating capacity is 15KW, can be for 5 tons of fresh-keeping and cold storages.
The heat energy of supposing water in the boiler 7 is to be Q3, and Q2 is that working medium is passed through the heat in the environment that evaporimeter 1 system absorbs, produces Q1 by compressor 2 power consumptions acting again.Enter by duplex matter system and to carry out heat release Q3, i.e. Q3=Q1+Q2 in the heat regenerator 5.The heat energy of Q3 flows in the boiler 7 by water pump 6 again, and when the water in the boiler 7 reached temperature requirement, auxiliary condenser 3 fan electromotors were opened externally cooling automatically, obtain hot water thus.Its operation principle is referred to as contrary Carnot cycle principle in physics.
The delivery port of boiler 7 (going out hot water) is connected two set of tubes with water inlet (advancing cold water).One cover is to link to each other with defrosting water pump 8, defrosting shower nozzle 10 by defrosting pipeline 9, and defrosting shower nozzle 10 is installed in evaporimeter 1 top, in addition, drip tray 12 has been installed also below evaporimeter 1, and drip tray one end is connected to the water inlet of boiler 7 by water pipe.Like this, utilize the hot water of exporting in the boiler 7 (Controllable Temperature of defrost water is built in for example 25 ℃) to be reached for the purpose of the evaporator defrost of freezer.The heat water-spraying to the evaporimeter after temperature descend, cold water accumulates in the drip tray 12, is back to the water inlet of boiler again, is heated once more in boiler, circulates with this.Another set of pipeline can connect domestic water equipment such as shower nozzle, can use for life.Cooperate 3 tons boiler can go out about 10 tons of hot water in 7,24 hours, enough supply 60-125 people's life or bathing and use.
Because the power consumption of electricity defrosting accounts for 2/5 of the total power consumption of equipment in the refrigeration plant, and security is not high, it is many to have an accident, therefore can utilize the heat of recovery to produce hot water by the utility model defrosts, greatly reduce the power of defrosting, its power consumption is 1/5 of electricity defrosting power consumption, promptly saves the 80% defrosting electricity charge.And safer, accident rate is low, and defrosting time is short, the storehouse temperature difference and thermic load is little, machine is short running time, has saved a large amount of electric energy.
The effect data of table 1 expression present embodiment and the effect data of other 4 kinds of models in addition.Because it is similar that the installation of equipment is arranged, and repeats no more herein.
Table 1
Annotate: the supposition environment temperature is 25 degree, and cold water temperature is 15 ℃, and the hot water temperature is 55 ℃, and the heat that then heating one ton of water needs is 4000 kilocalories.
