Description
Technical field
The utility model belongs to the refrigerating machine field; Relate to a kind of novel integral type air source and source, ground composite type heat pump installation technology; Specifically relate to a kind of air source and source, ground of using simultaneously as compound Cooling and Heat Source; Utilize the steam compression type refrigeration circulation, satisfy the heat pump assembly of the demand of room air adjusting.
Background technology
Along with the industrial development of current society and the raising of people's living standard; Commercial production and human settlements life also improve the requirement of traditional air-conditioning technical thereupon; On the basis of maintenance to the comfortableness requirement of aircondition, require it more energy-conservation, littler to the influence of environment.
" heat pump " technology is the HVAC technology of the comparison energy-saving and environmental protection of generally acknowledging.The mechanical power of heat pump consumption input just can be absorbed heat from low-temperature heat source, and heat release is to the elevated temperature heat source then, and heat pump is an operation principle with contrary Carnot cycle, defers to thermodynamics three big laws.When heating, heat pump can obtain low level heat energy through the circulation of thermal technology's working medium from water, air or the soil in the external world, and heat release is to indoor then, and the energy that heat pump itself consumes only accounts for the part of heating capacity; During refrigeration, heat pump can be from indoor heat absorption through the circulation of thermal technology's working medium, and heat release is to extraneous water, air or soil then, and the heat pump power consumption also only accounts for the part of refrigerating capacity.Because heat pump assembly is to the portion of energy of preserving in surrounding medium digging utilization in addition, therefore, heat pump techniques is considered to a kind of air-conditioning technical of energy-conserving and environment-protective.
According to the thermal source medium that evaporimeter in the heat pump circulating device adopts, the low-temperature receiver medium that condenser adopts is different, and heat pump generally has air source heat pump, water resource heat pump and several kinds of forms of earth source heat pump.The extensive at present heat pump that mainly is to use single Cooling and Heat Source that uses, they have advantage separately, but the shortcoming of some restrictions is arranged respectively.
Air source heat pump is with the Cooling and Heat Source of air as the realization cooling and warming; Generally make cold-producing medium and air directly carry out heat exchange as outdoor heat exchanger with fin-tube heat exchanger; Owing to there is not middle heat transferring medium; And the ubiquity characteristic of air, the structure of air source heat pump is comparatively simple, and it is also relatively low to make installation cost.But because the humiture of external environment changes, air source heat pump receives the restriction of environment bigger, and it is also bigger that the heat pump circulating system performance is influenced by air temperature variations.At north cold area, because the restriction of cold-producing medium evaporating temperature, even the situation that to use air source heat pump to heat occurs, and in southern humid area, the fin frosting also appears in winter heating easily, influences the situation of heat pump work.
Earth source heat pump (comprising soil source heat pump, enclosed water resource heat pump) as Cooling and Heat Source, is a kind of technology of using cleaning, regenerative resource with soil (perhaps underground water, surface water).The soil that earth-source hot-pump system uses or water temperature summer are lower than ambient air temperature generally at 18～32 ℃, and heat pump cycle condensation temperature (pressure) is lower, makes cooling effect be better than air source heat pump; And the soil that uses or water temperature winter generally at 12～22 ℃, be higher than ambient air temperature, heat pump cycle evaporating temperature (pressure) is higher, makes Energy Efficiency Ratio COP also be higher than air source heat pump.But; Earth-source hot-pump system winter, in some areas existed a quality heating cycle in heat radiation heat-obtaining uneven problem to the soil heat release winter from the soil extract heat; Show as heat radiation in south obviously greater than heat-obtaining, the soil moisture is along with the long-term use of earth-source hot-pump system raises year by year; Show as heat-obtaining in the north obviously greater than heat radiation, the soil moisture reduces year by year, and the temperature of soil worsens the property variation and causes the performance of system to produce a desired effect, and Energy Efficiency Ratio is along with reducing service time gradually, even the situation that earth source heat pump can't use occurs.In addition, because outdoor heat exchanger need use water or other fluid as middle heat transferring medium, need the investment of extra well-digging and tubing simultaneously, the manufacturing of earth-source hot-pump system and installation cost are often than higher.
Be to solve the uneven problem of heat radiation heat-obtaining that earth source heat pump uses appearance for a long time at present on the engineering; Mainly take extra method of appending auxiliary heat dissipation (heat-obtaining) equipment; Heat radiation is during greater than heat-obtaining; Use equipment auxiliary heat dissipations such as cooling tower, heat-obtaining uses the auxiliary heat-obtaining of equipment such as solar energy, boiler, electrical heating during greater than heat radiation.This method makes the cost of equipment and installation more increase.
Consult existing Patent data, Granted publication number is the utility model patent of CN 201706782U, and this utility model discloses the switchable heat pump circulating system of a kind of integrated heat source; This utility model has been arranged 2 evaporimeters in the circulation of prior steam compression-type refrigeration; One is the evaporimeter of water source heat exchanger, and one is the air source evaporimeter, in the use; Rely on the switching-over of three-way magnetic valve, realize the changeable of thermal source.This utility model has increased an evaporimeter, and the equipment pipeline of making is complicated more, and the burden of the frequent switch valve of increase system can not be used described 2 kinds of evaporimeters simultaneously.
The utility model patent of patent No. ZL 200720062510.7; This utility model provides a kind of water source/air source mixed type evaporation, condenser, and it passes refrigerant pipe and auxilliary pipe simultaneously in the fin of arranging, and flows to the heat radiation or the heat-obtaining of fin through waste water, waste gas, water source in the auxilliary pipe; Be used for defrosting to fin; With the cooling to fin, the design that this utility model is assisted pipe can not promote the efficient of freezing or heating circulation, assists flowing of pipe meeting blocks air on the contrary; Influence the exchange capability of heat of refrigerant pipe, the coefficient of performance of cooling and warming is descended.
