Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be more easy to
In being readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Refering to shown in Fig. 1, the present invention provides external source combined temperature difference hybrid refrigerating device in one, including compressor 4,
Condenser 6 and vaporizer 7, it also includes that power source the 1, first temperature difference power machine 2, hybrid power box 3 and second temperature difference are dynamic
Power machine 5, described power source 1 is connected with the first power shaft of hybrid power box 3, the output of described first temperature difference power machine 2
Axle is connected with the second power shaft of hybrid power box 3, the output shaft of described hybrid power box 3 and the first power of compressor 4
Input connects, and the described import of the second temperature difference power machine 5 is connected with the outlet of compressor 4, described second temperature difference power machine
The outlet of 5 is connected with the import of condenser 6, and the outlet of described condenser 6 is connected with the import of vaporizer 7, described evaporation
The outlet of device 7 is connected with the import of compressor 4, and the output shaft of described second temperature difference power machine 5 moves with the second of compressor 4
Power input connects.
As preferably, described first temperature difference power machine 2 and the second temperature difference power machine 5 are screw expander or turbo-expander.
As preferably, described power source 1 is motor, can use other power set.
In the present invention, the power of the first temperature difference power machine 2 can use hot water, steam-energy, waste heat energy, solar water,
Or solar steam can wait, specifically can select according to requirement actual when using.
The operation principle of the present invention is: in use, and motor normally drives compressor 4 to work, and compressor 4 is by the system of steam state
The liquid refrigerant of cryogen boil down to High Temperature High Pressure, then becomes the cold-producing medium of middle temperature high pressure by the second temperature difference power machine 5,
Partial heat drives the second temperature difference power machine 5 to do manual work to produce mechanical energy and drives compressor 4 to work (to follow in defining heat
Ring), the cold-producing medium of middle temperature high pressure is delivered to cool down in condenser 6, and subsequently into vaporizer 7, cold-producing medium steams in vaporizer 7
Absorbing substantial amounts of heat during Faing, vaporizer 7 primary side will turn cold, vaporizer 7 secondary side can produce chilled water or
Cold wind, to realize the purpose of refrigeration.And exchange by the pipeline of condenser 6 and vaporizer 7 by cross valve when heating
Get final product (only having this function as air-conditioning when using).
It is an advantage of the current invention that: disclosure satisfy that refrigerating plant (such as Central air-conditioning unit) works in external source as power input
Time, motor is standby, does not consume electric power.When external source inputs inadequate as power, motor is as auxiliary power warp
Jointly driving compressor after crossing mixing, because motor load is relatively light, electric current is less, and does not has the refrigerating plant of external source (such as central authorities
Air-conditioning) compare, substantial amounts of electric energy can be saved.
