Description

Source, a kind of carbon dioxide ground formula geothermal system
Technical field
The utility model belongs to cooling/warming system technical field, particularly relates to source, a kind of carbon dioxide ground formula geothermal system.
Background technology
Soil source heat pump utilizes the feature of soil temperature stabilization throughout the year, winter can as the thermal source of heat pump heating using soil, namely supply indoor heating is taken out higher than the heat energy in the ground energy of environment temperature, summer as the low-temperature receiver of air-conditioning, namely can take out soil and is discharged into the end in the soil of environment temperature the heat energy of indoor.Usually need in this system to take water as refrigerating medium for user provides cold and heat, comparatively large to water resources consumption, energy consumption is larger.
Summary of the invention
The defect that the utility model exists to overcome prior art, the purpose of this utility model is to provide source, the carbon dioxide ground formula geothermal system that a kind of energy-conserving and environment-protective, structure are simple, be applicable to northern severe cold weather.
The technical solution that the utility model adopts is source, a kind of carbon dioxide ground formula geothermal system, comprise CO 2 cross-critical compressor, oil eliminator, coil pipe, regenerator, expansion valve, U-tube and gas-liquid separator, the outlet of described CO 2 cross-critical compressor is connected with oil eliminator, described oil eliminator is connected with coil pipe, described coil pipe is connected with regenerator, described regenerator side is connected with the U-tube import being embedded in underground with expansion valve, described regenerator opposite side is connected with gas-liquid separator with the delivery outlet of the U-tube being embedded in underground, described gas-liquid separator outlet is connected with CO 2 cross-critical compressor.
Described coil pipe is arranged on below the ground surface in room.
The oil-out of described oil eliminator is connected with CO 2 cross-critical compressor with electronics oil balancer by oil strainer, is also provided with service valve between described oil eliminator and CO 2 cross-critical compressor.
The input of described coil pipe is provided with motor-driven valve.
This system can be widely used in the community, villa, hotel, hotel, office building etc. of heating, especially in the northern territory that land resource is abundant, it can reach the object of energy-saving and emission-reduction and saving operating cost simultaneously by not only reaching good heating effect, also the problem can not started shooting at low ambient temperatures for air source heat pump, provides good solution
Compared with prior art, the beneficial effect that the utility model has is:
1: carbon dioxide, as cold-producing medium, is the excellent green working medium of a kind of environmental-protecting performance, can reduces greenhouse effects and ozone layer degradation; Its COP value is greater than 4.0, and operating cost is very low, and carbon dioxide has excellent heat-conductive characteristic.So using the cycle fluid of carbon dioxide as thermal power plant unit, it will have remarkable heating capacity.
2: adopt the mode of underground heat not only can save careat and space, indoor heating homogeneous temperature can also be made.
3: whole cold is brought into underground by the mode of underground buried tube by this system, even if make its north in severe cold can be applied equally.
4: whole system structure is simple, makes its unit floor space little, save machine room space.

Detailed description of the invention
As shown in Figure 1, source, a kind of carbon dioxide ground formula geothermal system, comprise CO 2 cross-critical compressor, oil eliminator, coil pipe, regenerator, expansion valve, U-tube and gas-liquid separator, the outlet of described CO 2 cross-critical compressor is connected with oil eliminator, described oil eliminator is connected with coil pipe, described coil pipe is connected with regenerator, described regenerator side is connected with the U-tube import being embedded in underground with expansion valve, described regenerator opposite side is connected with gas-liquid separator with the delivery outlet of the U-tube being embedded in underground, described gas-liquid separator outlet is connected with CO 2 cross-critical compressor.Described coil pipe is arranged on below the ground surface in room.Source, carbon dioxide ground formula geothermal system adopts CO 2 cross-critical compressor, carbon dioxide under superheat state is sent into and is embedded in the underground coil pipe needing heat supply room, in room, heat radiation reaches the object allowing room temperature rise, because carbon dioxide condensation in overheat conditions has larger temperature glide, make it have good heating effect, carbon dioxide after being condensed continued to enter after the eruption of overexpansion valve to be unexpectedly embedded in the U-tube of underground through regenerator, get back to after sweat cooling overheated in regenerator after get back to CO 2 cross-critical compressor input, complete whole circulation.
The oil-out of described oil eliminator is connected with CO 2 cross-critical compressor with electronics oil balancer by oil strainer, is also provided with service valve between described oil eliminator and CO 2 cross-critical compressor.The input of described coil pipe is provided with motor-driven valve.
The selection of described magnetic valve and be set to the state of the art, those skilled in the art can carry out selecting and arranging according to prior art.
This system can have good heating effect, mainly utilize carbon dioxide as having good macroscopic property during cold-producing medium, especially when whole kind of refrigeration cycle be carry out under the condition at Trans-critical cycle time, the delivery temperature of carbon dioxide is higher, larger temperature glide can be there is after reducing temperature after it enters condenser, release a large amount of heats.In addition the mode of underground buried tube is utilized to bring cold into underground, even if make still can take this heat-supplying mode in northern frore area.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
