Integrated geo-source heat pump air-conditioning unit
Affiliated technical field
The utility model relates to geothermal heat pump air-conditioner, or claims water source heat pump air-conditioner; Specifically, relate to geothermal heat pump air-conditioner machine and water circulating pump integral type equipment.
Background technology
Earth source heat pump is a kind of air conditioner refrigerating and the heating new technology of external twentyth century the eighties rise.In China, the research of earth source heat pump starts from the last century the eighties to late nineteen nineties, and this technology has not only become the problem of the popular research of domestic air-conditioning circle, and begins to be applied in the engineering practice.Xiang Guan product also arises at the historic moment therewith, the domestic upsurge that starts one geothermal space conditioning.Up to the present, the manufacturer of the earth source heat pump of various brands does not descend dozens of.The indoor design and the installation form of these geothermal heat pump air-conditioner machines or water source heat pump air-conditioner machine exist following deficiency:
The first also includes only compressor in the present unit, condensing heat exchanger, and evaporating heat exchanger, expansion valve, four-way change-over valve and controller six big assemblies, and do not comprise water circulating pump.
It two is, water circulating pump needs to install in addition, for antifreeze, also will add a cover machine room for water circulating pump and air conditioner, to guarantee water pump and the normal operation of air-conditioning unit in winter.
Cause the unit floor space big thus, install, use all inconvenience.Domestic representational brand is as Shandong Bei Laite, Fu Erda geothermal heat pump air-conditioner machine series; Tsing Hua Tong Fang's water source heat pump air-conditioner machine series is not always the case.
The utility model content
At the problems referred to above, the utility model provides a kind of new geothermal heat pump air-conditioner unit indoor design structure and installation form thereof, to reduce the peripheral hardware water circulating pump and the inconvenience that brings to the user is installed; Make complete machine adapt to the requirement of outdoor installation simultaneously.
The purpose of this utility model is achieved in that
Integrated geo-source heat pump air-conditioning unit comprises casing (16), compressor (1), and condensing heat exchanger (2), evaporating heat exchanger (3), expansion valve (4), four-way change-over valve (5) also comprises cooling water pump (14) and chilled water pump (15);
Pipeline therebetween is connected to:
Refrigerant system pipeline: connect the four-way change-over valve high-pressure inlet under the exhaust outlet of compressor, connect the condensing heat exchanger import under the four-way change-over valve high-pressure outlet, connect the expansion valve import under the condensing heat exchanger outlet, connect the evaporating heat exchanger import under the expansion valve outlet, connect the four-way change-over valve low pressure inlet under the evaporating heat exchanger outlet, connect the compressor air suction mouth under the four-way change-over valve low tension outlet, lead to exhaust outlet of compressor again, form closed circulation;
Cooling water system pipeline: connect the side-entrance of condensing heat exchanger water under the cool cycles exit of pump, ground connection pipe laying water inlet flange under the condensing heat exchanger circulating water outlet flange, connect condensing heat exchanger circulating water intake flange under the ground pipe laying water out flange, connect the cooling circulating water pump inlet under the condensing heat exchanger circulating water outlet, arrive the cooling water cycle water pump discharge again, form the cooling water closed circulation;
Chilled water system pipeline: connect the side-entrance of evaporating heat exchanger water under the outlet of chilled water water circulating pump, connect end equipment water inlet flange under the evaporating heat exchanger circulating water outlet flange, connect evaporating heat exchanger circulating water intake flange under the end equipment water out flange, connect the import of freeze cycle water pump under the evaporating heat exchanger circulating water outlet flange, arrive the freeze cycle exit of pump again, form the chilled water closed circulation.
The constant pressure arrangement (13) that in above-mentioned integrated geo-source heat pump air-conditioning unit, also comprises water circulating pump.
When water temperature changed, the volume of water also changed thereupon, if be not provided with a shedding motion in airtight water circulation system, will cause the problem that rises, contracts and produce owing to water volume.The so-called constant pressure arrangement shedding motion in the water circulating pipe that is located at former sealing that comes to this.
In above-mentioned integrated geo-source heat pump air-conditioning unit, also comprise the antifreeze automaton of forming by temperature-sensing probe and pressure switch (12) that is serially connected between power supply and the pump motor; Wherein, the capillary of temperature-sensing probe communicates with pressure switch.
Antifreeze automaton can be located at outside the cabinet, so that maintenance; But preferably be located in the cabinet, so that record temperature in chassis accurately, and control starting mode of pump in view of the above.It is made up of temperature-sensing probe and pressure switch; A kind of refrigerant gas is housed in the probe, and the saturated vapor pressure of gas is corresponding with temperature, and the saturated vapor pressure of refrigerant gas raise when promptly temperature raise; The saturated vapor drops of refrigerant gas when temperature reduces.Pressure switch is a kind of switch by gas pressure control, promptly can set its switch connection when certain pressure, and switch disconnects when being raised to or dropping to certain pressure.Utilize the characteristic separately of temperature-sensing probe and pressure switch, the two is combined, just can constitute a temperature detect switch (TDS), the switch control relay is according to set temperature actuated or stop thus.
Owing to solved antifreeze problem, use integrated geo-source heat pump air-conditioning unit of the present utility model, can be directly installed on outdoor, and do not need to build in addition machine room, reduced floor space, saved the required expense of construction machine room, reduced the use cost of geothermal heat pump air-conditioner unit, for popularization, this energy-saving and environmental protection product of applying ground source heat pump air-conditioning unit have been created condition.
