Description
Technical field
The utility model relates to a kind of multi-source combined heat-pump heating system, belongs to central air conditioning project technical field.
Background technology
Conventional heat pump heating system mainly utilizes air-source or source, ground as thermal source, but existing various heat pump exists some drawbacks, during air source heat pump heating system is run in the winter time, if environment temperature is too low, evaporator surface frosting may be there is, the problems such as compressor start difficulty.Although earth source heat pump heating system has the earth as stable Cooling and Heat Source, this system requirements has certain pipe laying area and higher initial cost.Existing combined heat-pump heating system also just utilizes traditional source pump, connect different thermals source by evaporimeter and carry out work, although solve operational efficiency and cold thermally equilibrated technical problem to a certain extent, higher initial cost problem is not still better solved.
Summary of the invention
For above background technology, in order to solve China's winter heating better and alleviate the problems such as environmental pollution, solve the limitation of prior art, and meet the requirement of low-cost high-efficiency operation, this patent proposes a kind of brand-new multi-source combined heat-pump heating system.
The multi-source combined heat-pump heating system that the utility model proposes forms primarily of Multisource heat pump unit, user side circulating pump, user side water collecting and diversifying device, heat source side circulating pump and thermal source.Connected by pipeline between each assembly.Multisource heat pump unit is provided with two evaporimeters, is air-source evaporimeter and water source evaporimeter respectively.Water source evaporimeter can connect various water source (comprise in solar water, earth source heat pump in underground pipe recirculated water, surface water, sewage) by pipeline.Multisource heat pump unit is also provided with temperature sensor and motor switch, is regulated and controled the operation of double evaporators by temperature signal.Water source vaporizer side in Multisource heat pump unit connects two or more thermal source.The signals-modulating that air-source evaporimeter in Multisource heat pump unit is transmitted by temperature sensor is opened, is closed.
The utility model solves the technical scheme that its technical problem adopts: Multisource heat pump train condenser, user side water collecting and diversifying device are connected by pipeline with user side circulating pump, provide power, by the carry heat in condenser to user's end by user side circulating pump.Multisource heat pump unit water source evaporimeter, heat source side circulating pump and thermal source are connected by pipeline, provide power by carry heat in thermal source to the cold-producing medium in evaporimeter by heat source side circulating pump.Temperature sensor and motor switch is provided with in Multisource heat pump unit, the unlatching of double evaporators is regulated and controled by temperature sensor, more than outdoor temperature T >=7 DEG C, the temperature signal of temperature sensor transmission changes the signal of telecommunication into and acts on motor switch startup air-source evaporimeter, as outdoor temperature < less than 7 DEG C, close air-source evaporimeter, only have water source evaporator operation.Water source evaporator inlet-outlet joinably source heat pump ground pipe laying, solar thermal collector, surface water, sewage as the water source of thermal source.Evaporation side can connect single source, and need to connect composite heat power supply in the uneven situation of structure trunk cooling and heating load, concrete condition is according to the actual execution of engineering.
The beneficial effects of the utility model are: the source pump design of (1) double evaporators can utilize air-source and two kinds, the water source energy simultaneously, effectively improves the Energy Efficiency Ratio of unit.(2) use of air-source greatly reduces the cost of investment of heat pump.(3) water source vaporizer side can connect various heating sources form, improves the operational efficiency of heat pump.
