Abstract
The utility model discloses a CO2 heat pump central heat supply device comprising a CO2 heat pump circulating device and a heat supply pipeline, the CO2 heat pump circulating device is formed by successively circulating connection of a compressor, a gas cooler, a throttle valve, a liquid storage tank and an evaporator, and the heat supply pipeline is communicated with the gas cooler. Trans-critical compression is achieved by the CO2 heat pump, high-temperature hot water (65 DEG C-75 DEG C) is prepared, and high-temperature hot water demand is satisfied by large temperature difference high-temperature heating, thereby filling in domestic blanks in projects such as industry, business and civil use and the like.
Description
Technical field
The utility model relates to central air-conditioning technical field, especially a kind of CO
2heat pump central heating plant.
Background technology
Tradition control model adopts forced circulation, and it is all the large flow of the little temperature difference substantially that Natural Circulation is prepared hot water, cannot solve high temperature and need water (65 ℃～75 ℃); All few at subcritical cycle thermal discharge owing to limiting to again traditional refrigerant, pressure ratio is large, delivery temperature restriction, and traditional control model can not realize high temperature and need water.
Utility model content
The utility model, for the deficiencies in the prior art, proposes a kind of CO
2heat pump central heating plant, can realize the requirement that high temperature needs water.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme: a kind of CO
2heat pump central heating plant, comprises CO
2heat pump circulating device and heat supply pipeline, described CO
2heat pump circulating device is circulated and connects and composes successively by compressor, gas cooler, choke valve, fluid reservoir and evaporimeter; Described heat supply pipeline is communicated with described gas cooler.
Further, be provided with successively water pump, removing scale by strong magnetic field instrument, Si-P crystal descaler and water tank on described heat supply pipeline, described Si-P crystal descaler outlet is connected with described gas cooler.
Further, described water pump is frequency conversion small pump.
Compared with prior art, the utlity model has following advantage: CO
2heat pump is realized across critical compression, produces high-temperature-hot-water (65 ℃～75 ℃), realizes large temperature difference high temperature and heats the high-temperature-hot-water demand that solves, and in industry, business, the project such as civilian, fills the domestic gaps.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of CO as shown in Figure 1
2heat pump central heating plant, comprises CO
2heat pump circulating device 1 and heat supply pipeline 2, described CO
2heat pump circulating device 1 is circulated and connects and composes successively by compressor 11, gas cooler 12, choke valve 13, fluid reservoir 14 and evaporimeter 15; Described heat supply pipeline 2 is communicated with described gas cooler 12.
On described heat supply pipeline 2, be provided with successively water pump 21, removing scale by strong magnetic field instrument 22, Si-P crystal descaler 23 and water tank 24, described Si-P crystal descaler 23 outlets are connected with described gas cooler 12.Described water pump 21 is frequency conversion small pump.
The utility model device has and heats and two kinds of functions of heat accumulation, draws high-temperature-hot-water.CO
2air source heat pump is produced high-temperature-hot-water (65 ℃～75 ℃).Frequency conversion small pump is controlled constant temperature variable-flow regulating water flow function.Removing scale by strong magnetic field device, cold water enters the front descaling function of main frame.Si-P crystal secondary is softening, descaling function.Stainless steel attemperater meets hot water and realizes deposit, temperature (65 ℃～75 ℃); The method solves the needs of industry, business, civilian project high-temperature-hot-water.
