Machine.
Background technique
China belongs to large agricultural country, and fruits and vegetables cultivated area is larger, after harvest as storage be not good at will lead to it is rotten, cause greatly
Waste.Therefore, with the fast development of China's Food Cold Chain, freezer construction in various regions is increasing, and fruits and vegetables are stored in freezer
It is interior effectively to extend the shelf life.However freezer and farmland are apart from each other mostly, fresh fruit of vegetables has a large amount of field heat, fruit again
Vegetable is in transit higher temperature, to fresh-keeping totally unfavorable.Meanwhile China mostly uses electric heating or boiler heating method
Resident living hot water is produced, a large amount of high-grade energies are consumed, causes great energy waste, the energy with China's energy-saving and emission-reduction
Source policy is seriously runed counter to.If above-mentioned fruits and vegetables field heat can be used to domestic hot-water produce, it will greatly improve the benefit of thermal energy
With rate.

The problem of effective use cannot be obtained.
To achieve the above object, the utility model can take following technical proposals:
Vacuum pre-cooling heat pump water heater integrated machine described in the utility model, including sequentially connected compressor, condenser,
Throttle valve, evaporator and gas-liquid separator, the evaporator are arranged in condensate room, the gas inlet tube of the condensate room and fruit
Vegetable locker room is connected, and is connected with vaccum stop valve and vacuum pump, the bottom row of condensate room on the gas outlet tube of condensate room in turn
Water pipe is connected by condensate drain valve with water storage box；It is provided between the water storage box and the condenser with water circulating pump
Circulation line, be provided with hot water drainpipe and the moisturizing water inlet pipe with ball-cock assembly on water storage box.
Vacuum pre-cooling heat pump water heater integrated machine provided by the utility model, structure is simple, easy to use, by vacuum pre-cooling
Technology and heat pump techniques combine, while quickly removing the heat of fruits and vegetables using the evaporation of water, and the condensation heat of vapor
It is converted into the sensible heat of water, since the latent heat of 1kg water is about 590 times of sensible heat, the higher life heat of temperature can be produced
Water, to achieve energy-saving and emission reduction purposes.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, vacuum pre-cooling heat pump water heater integrated machine described in the utility model, including vacuum pre-cooling system,
Refrigeration system and hot-water heating system.Specifically, including sequentially connected compressor 1, condenser 2, throttle valve 3, evaporator 4 and gas-liquid
The refrigeration system that separator 5 is constituted；In addition, evaporator 4 is mounted in condensate room 6, gas inlet tube and the fruits and vegetables of condensate room 6 are deposited
Storage chamber 7 is connected, and is connected with vaccum stop valve 8 and vacuum pump 9, above-mentioned fruits and vegetables locker room on the gas outlet tube of condensate room 6 in turn
7, condensate room 6, vaccum stop valve 8 and vacuum pump 9 form vacuum pre-cooling system；The main body of hot-water heating system includes water storage box 11, is stored
Water tank 11 is connected by condensate drain valve 10 with the drainpipe of 6 bottom of condensate room, is provided between water storage box 11 and condenser 2
Circulation line with water circulating pump 12 is provided with hot water drainpipe 13 and the moisturizing water inlet with ball-cock assembly 14 on water storage box 11
Pipe 15.In order to reduce cooling capacity and thermal loss, above-mentioned hot water circulating pipeline and condensate recovery pipe etc. make isothermal holding.
In use, first fruit and vegetable food is placed in fruits and vegetables locker room 7, condensate drain valve 10 is closed, opens vacuum cut-off
Valve 8 and vacuum pump 9 after vacuum pre-cooling system forms certain vacuum degree, close vaccum stop valve 8 under the action of vacuum pump 9
With vacuum pump 9, the moisture of fruit and vegetable surfaces rapid evaporation endothermic under vacuum conditions makes fruits and vegetables temperature be quickly reduced to the temperature of requirement
Degree；In order to maintain the vacuum degree of chilldown system, evaporates the moisture of fruit and vegetable surfaces persistently, open refrigeration system at this time, pass through steaming
Hair device 4 makes the vapor evaporated in vacuum pre-cooling system be condensed into liquid water again, to complete the cooling of fruits and vegetables, pre-cooling is finished
Condensate drain valve 10 is opened afterwards, is discharged into the condensed water in vacuum pre-cooling system in water storage box 11.
After opening refrigeration system, refrigerant becomes high-temperature high-pressure refrigerant steam by compressor 1 and enters water-cooled condensation
Device 2, is condensed into the refrigerant liquid of high pressure medium temperature after 2 heat release of condenser, while refrigerant condensing heat being discharged to circulation
Water increases the temperature of recirculated water, and then liquid refrigerant is expanded to the gas-liquid two-phase refrigeration of low-temp low-pressure by throttle valve 3
Agent, the gas-liquid two-phase cold-producing medium of low-temp low-pressure become the steam of low-temp low-pressure after entering 4 evaporation endothermic of evaporator or have a small amount of
The gas-liquid two-phase of liquid, while the vapor in vacuum pre-cooling system being made to be condensed into liquid water, remain true in vacuum pre-cooling system
Then the vacuum degree of empty room separates a small amount of liquid refrigerant that there are bottoms by gas-liquid separator 5, gas is through compressor
1 air entry enters inside compressor, thus completes refrigerant circulation.
While freezing unlatching, opens or open water circulating pump 12 in advance, the water in water storage box 11 will be placed in advance in
It is pumped into the condensation heat for absorbing refrigerant in water-cooled condenser 2, is after water temperature increases, to return to water storage box 11, hot water is consequently formed and follows
Loop system.
By vacuum, technology is combined with heat pump techniques the utility model to the cold, while fruits and vegetables are pre-chilled, produces domestic hot-water,
By reasonable energy utilization, achieve energy-saving and emission reduction purposes.
Compared with prior art, its advantages are specific as follows:
1, by heat pump techniques by the heat dissipation of food in vacuum pre-cooling into water, produce domestic hot-water, rationally utilize
The energy；
2, dexterously the latent heat of water is converted to the sensible heat of water, the temperature of food had both been reduced by the latent heat of phase change of water, has been reached
To fresh-keeping effect, and the temperature of water itself is improved, hot water preparing provides a kind of utilization theory of latent heat change sensible heat；
3, the efficiency that the cold recovery of condensate can be improved to refrigeration system into condenser system reaches energy-efficient purpose；
4, compared with traditional food cooling system, structure is simple, flexible in application, and can solve field and lack asking for hot water
Topic.
