The utility model is exactly for above-mentioned shortcoming, and a kind of geothermal heat pump air-conditioning system with flow regulating function is provided.
The technical scheme that the utility model adopts is as follows: the geothermal heat pump air-conditioning system with flow regulating function, comprise outdoor ground energy heat-exchange system, Water source heat pump unit group system and indoor air-conditioning system, carry out heat transfer with water as heat transferring medium between described three systems, described outdoor ground can heat-exchange system be vertical buried pipe heat exchange system, and the pipeline flow bascule is housed on the pipeline of described vertical buried pipe heat exchange system.
Further, described pipeline flow bascule is flow control valve.
The beneficial effects of the utility model are: (1) has many-sided advantages such as economy, energy-saving and environmental protection; (2) flow balance valve is once finished the pipe network Flow-rate adjustment, transferring net work to become simple assignment of traffic, effectively solves the hydraulic equilibrium imbalance of pipe network; (3) can be directly according to setting flow; (4) overcome system's phenomenon uneven in temperature, improve heat supply (cooling) quality.
Description of drawings
Fig. 1 is systematic schematic diagram of the present utility model.
In the accompanying drawing: 1-flow control valve; 2-outdoor ground energy heat-exchange system; 3-buried pipe; 4-evaporimeter; 5-condenser; 6-Water source heat pump unit group system; 7-indoor air-conditioning system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of geothermal heat pump air-conditioning system with flow regulating function comprises outdoor ground energy heat-exchange system 2, Water source heat pump unit group system 6 and indoor air-conditioning system 7, carries out heat transfer with water as heat transferring medium between described three systems.
Water source heat pump unit group system 6 comprises evaporimeter 4, condenser 5, compressor, expansion valve, cross valve.
Winter, the compressor of Water source heat pump unit group system 6 does work to refrigerant, make refrigerant become high temperature and high pressure gas and enter condenser 5, emit heat to indoor air-conditioning system 7, become mutually the liquid of HTHP, the liquid that becomes low-temp low-pressure through the expansion valve reducing pressure by regulating flow again enters evaporimeter 4, from outdoor ground energy heat-exchange system 2 draw heats, become mutually the saturated vapor of low-temp low-pressure, enter the compressor air suction end, finish a circulation.Constantly be transferred in the indoor process at underground heat, with indoor heating air conditioning terminal system to indoor heating.
Summer, the cross valve of Water source heat pump unit group system 6 changes mutually the function of evaporimeter 4, condenser 5 commutation of refrigerant flow direction, by underground pipe heat is discharged in the soil, refrigerant temperature is reduced supply with the earth source heat pump unit, give indoor cooling by source pump again.
Outdoor ground can heat-exchange system 2 be vertical buried pipe heat exchange system, the concrete pipe laying mode of burying of standing that adopts, as cold and hot loading gage body, in the heat exchange pipeline of water in being embedded in soil and circulate between source pump, realize the exchange heat between unit and the earth soil with water.
Flow control valve 1 is housed on the pipeline of vertical buried pipe heat exchange system, flow control valve 1 can be directly according to setting flow, can eliminate simultaneously residual head and the caused flow deviation of pressure oscillation of pipeline, no matter how system pressure changes all keeps the setting flow constant, the pipe network Flow-rate adjustment is once finished, transferring net work to become simple assignment of traffic, effectively solve the hydraulic misadjustment of pipe network.
The geothermal heat pump air-conditioner technology is to utilize solar energy that shallow surface water source (underground water, river, river, lake, sea) soil absorbs and geothermal energy and the low temperature Lowlevel thermal energy that forms, adopt heat pump principle, electric energy output by a small amount of realizes a kind of technology that Lowlevel thermal energy shifts to high level heat.The temperature of ground energy or shallow surface geothermal energy resources is relatively stable throughout the year, winter is higher than ambient air temperature, summer is lower than ambient air temperature, good source heat pump heat and cold source of air conditioning, therefore this temperature characterisitic is wanted energy-conservation and is saved operating cost about 40% so that earth source heat pump is higher by 40% than traditional air-conditioning system operational efficiency.
