Description
Technical field
This utility model is related to heating machine set field, especially a kind of ground source for changing clean energy resource suitable for northern country coal
Source pump.
Background technology
At present, northern vast rural area warming almost all is heated in the form of coal-burning boiler with radiator, due to
Coal-burning boiler produces substantial amounts of pollutant, is the principal element for causing environmental pollution, therefore prohibits the use of coal-burning boiler, rural area
Heating adopts clean energy resource.And low-temperature air source heat pump is due to its energy-saving and environmental protection, therefore will be used widely.Commonly
During the source pump Winter heat supply of source, there is provided 45 DEG C of hot water, and in -12 DEG C of ambient temperature, supply water temperature can also be reduced, mark
Standard is defined as 40 DEG C, it is adaptable to the heating on fan coil units or floor.Radiator is adopted the heating present situation in rural area at present more, if
Using conventional cryogenic air source source pump, for by radiator heating, 45 DEG C of hot water obviously can not meet requirement,
Heating requirement cannot be more met when ambient temperatures are low.If wanting rural area every family to change end-equipment, invest too high, do not have
The economic bases of realization.
Utility model content
Technical problem to be solved in the utility model be to provide it is a kind of improve supply water temperature suitable for northern country coal
Change the earth source heat pump unit of clean energy resource.
This utility model solves the technical scheme adopted by its technical problem：One kind changes cleaning suitable for northern country coal
The earth source heat pump unit of the energy, it is including heat-flash type compressor, condenser, flash vessel, expansion valve, capillary tube and vaporizer, described
Compressor is provided with low pressure refrigerant import, high temperature refrigerant outlet and steam inlet, and it is cold that the flash vessel is provided with middle compacting
Agent import, the outlet of middle compression refrigerant and steam (vapor) outlet, the high temperature refrigerant outlet of the compressor, condenser, capillary tube, flash distillation
The low pressure refrigerant import of the middle compression refrigerant import of device, the outlet of middle compression refrigerant, expansion valve, vaporizer and compressor phase successively
Connection forms loop, and the steam inlet of the middle compression refrigerant import, steam (vapor) outlet and compressor of the flash vessel is sequentially communicated；Institute
Condenser connection user pipe is stated, the vaporizer connects underground pipe.
The beneficial effects of the utility model are：The heating effect of the unit is good, and the leaving water temperature of user pipe can reach
55 DEG C, the hot water demand of resident can be met well.
Description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is further illustrated.
As shown in figure 1, a kind of earth source heat pump unit for changing clean energy resource suitable for northern country coal of the present utility model, bag
Heat-flash type compressor 1, condenser 2, flash vessel 3, expansion valve 4, capillary tube 6 and vaporizer 5 is included, the compressor 1 is provided with low
Compression refrigerant import 11, high temperature refrigerant outlet 12 and steam inlet 13, the flash vessel 3 are provided with middle compression refrigerant import
31st, middle compression refrigerant outlet 32 and steam (vapor) outlet 33, the high temperature refrigerant outlet 12, condenser 2, capillary tube of the compressor 1
6th, the low pressure system of the middle compression refrigerant import 31 of flash vessel 3, the outlet 32, expansion valve 4 of middle compression refrigerant, vaporizer 5 and compressor 1
Cryogen import 11 is sequentially connected to lead to and forms loop, the middle compression refrigerant import 31 of the flash vessel 3, steam (vapor) outlet 33 and compressor
1 steam inlet 13 is sequentially communicated；The condenser 2 connects user pipe, the connection underground pipe of the vaporizer 5.
, using Copeland Corp ZW series heat-flash type compressors, compression efficiency is high, it is possible to increase cold-producing medium for heat-flash type compressor 1
Temperature.Flash vessel 3 and capillary tube 6 realize quasi- two-stage compression and second vapor injection, effectively increase the compression efficiency of compressor 1,
Unit heating capacity is improved simultaneously, is that users reduce power load.One-level throttling substitutes original electronics using capillary tube 6
Expansion valve, while performance is met, unit cost is substantially reduced.Vaporizer 5 and condenser 2 adopt plate type heat exchanger, full
While sufficient heat exchange property, unit volume is little, and installing space is close to original coal-burning boiler and takes up room.During heating operation, compressor 1
High temperature refrigerant is entered into condenser 2 by high temperature refrigerant outlet 12, high temperature refrigerant in the condenser 2 with user side water pipe
In cold water heat exchange, raise cold water temperature, provide the user hot water.After cold-producing medium is condensed in condenser 2, Jing capillary tubies 6
By middle compression refrigerant import 31 into flash vessel 3 after one-level throttling, the saturated vapor of shwoot is gone out by steam in the flash vessel 3
The QI invigorating chamber of compressor 1 is sprayed into after mouth 33 and steam inlet 13, increases circulating mass of refrigerant, improve heating performance.Flash vessel 3
The expanded valve 4 of interior saturated solution enters vaporizer 5 after throttling, and is exchanged heat with the water from underground pipe, the gaseous refrigerant after evaporation
Agent returns to the low-voltage high-temperature refrigerant inlet 11 of compressor 1, completes to heat circulation.It is so uninterrupted to circulate, it is that user persistently carries
Supplying hot water.
Unit after improvement, Jing test and using checking, vaporizer 5 water inlet for 10 DEG C when, heat water outlet for 55 when, heat
COP ＞ 3.0, even up to 3.2, meet the requirement of energy-conserving and environment-protective, are adapted to the needs that rural area coal changes clean energy resource completely.
Preferred embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for this
For the technical staff in field, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. are should be included within protection domain of the present utility model.
