Description
One, technical field:
The utility model relates to a kind of heating, specifically is a kind of carbon dioxide heat-pump system.
Two, background technology:
At present, carbon dioxide heat-pump mainly by compressor, gas cooler, Intermediate Heat Exchanger, electric expansion valve, evaporimeter and gas-liquid separator are formed, the low-pressure side carbon dioxide enters compressor, be compressed into high-pressure carbon dioxide gas, enter the gas cooler heat release then, hot water is heated, entering Intermediate Heat Exchanger through the cooled carbon dioxide of gas cooler further cools off, pass through the throttling step-down of electric expansion valve then, become gas-liquid mixture and enter evaporimeter, after the air heat exchange of the evaporimeter of flowing through, enter gas-liquid separator, and then enter Intermediate Heat Exchanger and further heat, absorbed compression by compressor again, thereby realize a complete circulation.But when critical-temperature was 31 ℃ of left and right sides, the high-pressure side of systemic circulation was in nearly critical or supercriticality under the normal temperature cooling condition, and system pressure is very high, and restriction loss is very big, has very big drawback in practical operation.
Three, summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of firing rate fast, the carbon dioxide heat-pump system that temperature is high.
Its technical scheme is: the utility model comprises compressor, gas cooler, evaporimeter, Intermediate Heat Exchanger, electric expansion valve, gas-liquid separator, it is characterized in that: compressor is communicated with gas cooler, gas cooler is communicated with evaporimeter, evaporimeter is communicated with Intermediate Heat Exchanger, Intermediate Heat Exchanger is communicated with electric expansion valve, electric expansion valve is communicated with evaporimeter, the evaporimeter gas-liquid separator, the gas-liquid separator Intermediate Heat Exchanger, the Intermediate Heat Exchanger compressor, wherein, described compressor is a semi-hermetic piston-type compressor, and described evaporimeter is an evaporator fin.
Effect of the present utility model is: firing rate is fast, and the temperature height is pollution-free, and has energy-saving effect.
Four, description of drawings:
Accompanying drawing is a workflow diagram of the present utility model.
Five, the specific embodiment:
With reference to accompanying drawing, the utility model comprises compressor, gas cooler, evaporimeter, Intermediate Heat Exchanger, electric expansion valve, gas-liquid separator, it is characterized in that: compressor is communicated with gas cooler, gas cooler is communicated with evaporimeter, evaporimeter is communicated with Intermediate Heat Exchanger, Intermediate Heat Exchanger is communicated with electric expansion valve, electric expansion valve is communicated with evaporimeter, the evaporimeter gas-liquid separator, the gas-liquid separator Intermediate Heat Exchanger, the Intermediate Heat Exchanger compressor, wherein, described compressor is a semi-hermetic piston-type compressor, and described evaporimeter is an evaporator fin.
The utility model heats flow process:
1) the HTHP carbon dioxide coolant of compressor 1 discharge enters gas cooler 2 heat hot water;
2) carbon dioxide coolant that comes out from gas cooler 2 enters evaporimeter 3 and further cools off;
3) going out 3 carbon dioxide coolant from evaporimeter enters Intermediate Heat Exchanger 4 and carries out heat exchange;
4) the carbon dioxide coolant process electric expansion valve 5 throttling step-downs of coming out from middle heat exchanger 4 become gas-liquid mixture;
5) carbon dioxide coolant that comes out from electric expansion valve 5 enters evaporimeter 3 absorption heats;
6) carbon dioxide coolant that comes out from evaporimeter 3 enters gas-liquid separator 6;
7) carbon dioxide coolant that comes out from gas-liquid separator 6 enters Intermediate Heat Exchanger 4 and is heated;
8) carbon dioxide coolant that comes out from middle heat exchanger 4 is absorbed by compressor 1, realizes that one complete heats circulation.
In this flow process, adopted carbon dioxide coolant to come out from gas cooler 2 after, enter evaporimeter 3, enter the method for Intermediate Heat Exchanger 4 again.
Can enter first row of the windward side of evaporimeter 3 from the carbon dioxide that enters evaporimeter 3 after gas cooler 2 comes out, also can be any row.
From entering the carbon dioxide of evaporimeter 3 after gas cooler 2 comes out, can be a comb of evaporimeter, also can be the two or more rows pipe.
Heat and to use the carbon dioxide heat-pump system to obtain the hydronic purpose of high-temperature-hot-water (50 ℃-90 ℃) by carrying out novel carbon dioxide heat-pump system.
