Description

The liquid gas refrigerating plant

The utility model relates to a kind of liquid gas refrigerating plant, is specially adapted to the refrigeration of central air conditioner system and freezer and vehicle-mounted ice chest.

At present, in freezing and air-conditioning system, mostly use mechanical refrigeration and lithium bromide absorbing type refrigeration mode.Mechanical refrigeration utilizes refrigeration machine to realize that the cold-producing medium of use has ammonia and freon.As everyone knows, freon has destruction to ozone layer, is a kind of cold-producing medium that is under an embargo and uses in future, the lithium bromide absorbing type refrigeration that thereupon grows up, though desirable for freon, lithium-bromide solution remains chemical products, in various degree still there is pollution in environment.In addition, lithium bromide absorption refrigeration needs coal-fired steam or fuel Heating, the former fire coal, produce sulfur dioxide and volume of smoke, cause severe contamination to atmosphere, latter's great amount of fuel oil, can produce carbon monoxide, to the airborne release pernicious gas, still atmosphere be produced and pollute as vehicle exhaust.

The purpose of this utility model is at the problems referred to above, and non-environmental-pollution when a kind of application is provided, structural design is simple, volume is little, cost price is low, consumes the few liquid gas refrigerating plant of the energy.

The technical scheme that realizes above-mentioned purpose is: a kind of liquid gas refrigerating plant that includes liquefied gas at low temp basin and transfer pipeline is provided, its liquefied gas tank has outer tank body and interior tank body, on interior tank body, be provided with topping up pipe, formation loop that also disposes valve body outside leading to outside the tank body respectively and the liquid pipe that in this loop, is connected in series Pressure gauge and liquid level gauge, formation loop and in this loop, be connected in series the liquid pipe of vaporizer and the woven hose that is equipped with temperature control valve, its transfusion pipe end is connected with cooling grid, is provided with blast pipe at the not end of evaporimeter comb.

The technical solution of the utility model also comprises: described evaporimeter is placed in one and has in the sealing flume that is incubated interlayer, and the bottom of this tank is provided with the feed pipe of assembling water supply pump, is provided with return pipe on the top of tank.

Vaporizer described in the utility model mainly constitutes by establishing fin on the snakelike comb.

This liquid gas refrigerating plant adopt temperature greatly the liquid gas about about-200 ℃ as cold-producing medium, utilizing this cryogenic liquid evaporation to discharge the cold that produces removes frozen food or produces low-temperature cold water realization air-conditioning, because its raw material is the nexhaustible air of getting to the greatest extent, and because of the transportation of its present cryogenic liquid with store also very ripe and economical, so be used for central air conditioner system and freezer, ice chest refrigeration cost is lower, and remain air because of what it emitted at last, so do not have any pollution sources and pollutant, can be referred to as green refrigeration.

The utility model is compared with lithium bromide absorbing type refrigeration with existing mechanical refrigeration has following advantage:

1, equipment investment is low.Compare with the air-conditioning equipment one-time investment with present conventional refrigeration and to be about 1: 20 times.

2, not electricity consumption.Can remove the electricity consumption expense of increasing capacity of user's writing from.

3, device structure is simple, convenient operating maintenance.

4, cooling tower cooling system, water and electric saving have been removed.

5, whole plant area area is very little, the great amount of investment that can save the civil engineering machine room.

6, realize that the low-temperature deep quick-frozen is simply easy, help fresh-keeping, guarantor's flavor of food.

Accompanying drawing 1 is this liquid gas refrigerating plant structure and is applied to the central air conditioner system schematic diagram;

Accompanying drawing 2 is that this device is applied to freezer and vehicle-mounted ice chest refrigeration structural representation.

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, this device has outer tank body 1 and interior tank body 2, and the top of tank body is provided with between safety diaphragm 21, two tank bodies and forms vacuum chamber through evacuation tube 23 and valve body 24 outside.Be connected with topping up pipe 3 and completely put pipe 22 on the top of interior tank body and lead to outside the outer tank body, and respectively through

valve body

27 and 25 controls to the jar internal-filling liquid and control the liquid level limit.Interior tank body is provided with two ends and is communicated with the upper and lower respectively and constitutes the loop and place outer tank body outer liquid pipe 4 and liquid pipe 7, is serially connected with Pressure gauge 5 and liquid level gauge 6 in the loop of liquid pipe 4, and disposes

control angle valve

18,17,19 and 20 respectively; In the loop of liquid pipe 7, be serially connected with the vaporizer 8 that mainly constitutes by establishing fin on the snakelike comb, be used for the refrigerating fluid in the vaporizer being vaporized by normal temperature air, the required infusion pressure of tank body in providing, and dispose valve body 29,41 and valve body 34, control valve 31 and 40 and safety valve 42 respectively at the two ends of vaporizer.The bottom of tank body in woven hose 9 is connected, and dispose

valve body

28 and 26, be used to control the shutoff and the blowdown of woven hose.The other end of woven hose 9 is connected with cooling grid 11, and the end of evaporimeter 11 combs is provided with blast pipe 12, and disposes air bleeding valve 37 and be used to control gas purging in the evaporimeter.On the woven hose of evaporimeter front portion, dispose temperature control valve 10, be provided with supplying valve 30, check-valves 32, safety valve 33 and choke valve 35, stop valve 36 in the both sides of temperature-sensing valve.Provide as accompanying drawing 1, when this refrigerating plant is used for central air conditioner system, its evaporimeter 11 is placed in one and has in the sealing flume 13 that is incubated interlayer, feed pipe 14 is set in the bottom of this tank and disposes water supply pump 15, on the top of tank return pipe 16 is set, feed pipe is connected with air-conditioner system with return pipe, can provides air-conditioning required about about 7 ℃ circulating water to air conditioner with blower and coiled tube 38.
