Abstract
The utility model relates to a novel double-source heat pump which comprises a compressor, a condenser, a first expansion valve, an air source evaporator, a three-way valve, a second expansion valve and a second evaporator. The inlet of the three-way valve is connected with the refrigerant outlet end of the condenser. Two outlets of the three-way valve are respectively connected with the inlet of the air source evaporator through the first expansion valve and connected with the inlet of the second evaporator through the second expansion valve. A first drying filter and a moisture tester are arranged between the condenser and the three-way valve, and the moisture tester is further connected with a second drying filter. According to the novel double-source heat pump, a water source or air source is selected for providing heat for low-temperature evaporation of refrigerants according to heat source situations, flexibility and convenience are achieved, and the advantages of high energy efficiency of the water source heat pump and the advantages of maintaining heat pump work even under low environment temperatures of the air heat pump can be fully developed according to environment temperature situations.
Description
Technical field
The utility model relates to a kind of novel double-source heat pump.
Background technology
In actual applications, air source heat pump and water resource heat pump respectively have advantage to have water source temperature compared with air-source temperature stabilization as water resource heat pump, and efficiency is high, water resource heat pump can connect air-conditioning system and do recuperation of heat etc., and air source heat pump and its advantage of water resource heat pump comparison are when water source temperature final result zero degree, while not having enough heats to make evaporation thermal source, air source heat pump can absorb the work of air heat energy maintaining heat pump operation under subzero more than 10 ℃ temperature.Owing to adopting single source version, there is the intrinsic defect of single source, and can not give full play to the advantage of air source heat pump and water resource heat pump in existing heat pump.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of novel double-source heat pump is provided.
The utility model is achieved through the following technical solutions: a kind of novel double-source heat pump, comprise compressor, condenser, the first expansion valve, air-source evaporimeter, triple valve, the second expansion valve and the second evaporimeter, described triple valve import is connected with described condenser refrigerant outlet end, the import that two outlets of described triple valve are connected with described air-source evaporimeter through described the first expansion valve respectively, through described the second expansion valve, be connected with the import of described the second evaporimeter, the outlet of described the second evaporimeter is connected with the import of described compressor, between described condenser and described triple valve, be provided with the first device for drying and filtering and moisture tester, on described moisture tester, be also connected with the second device for drying and filtering.
As preferably, described the first expansion valve and the second expansion valve are heating power expansion valve or electric expansion valve.
As preferably, inner physical absorption drier and the chemisorbed drier of adopting of described the first device for drying and filtering and the second device for drying and filtering.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by installing light sensor in diffuser surface, can be according to thermal source situation, the low-temperature evaporation that choice for use water source or air-source are cold-producing medium provides heat, flexibly and easily, can be according to the situation of ambient air temperature, give full play under the high energy efficiency of water resource heat pump and the low environment temperature of air heat pump still can maintaining heat pump work advantage.

As shown in Figure 1, the utility model relates to a kind of novel double-source heat pump, comprise compressor 2, condenser 4, the first expansion valve 7, air-source evaporimeter 1, triple valve 6, the second expansion valve 5 and the second evaporimeter 3, described triple valve 6 imports are connected with described condenser 4 refrigerant outlet ends, the import that two outlets of described triple valve 6 are connected with described air-source evaporimeter 1 through described the first expansion valve 7 respectively, through described the second expansion valve 5, be connected with the import of described the second evaporimeter 3, the outlet of described the second evaporimeter 3 is connected with the import of described compressor 2, between described condenser 4 and described triple valve 6, be provided with the first device for drying and filtering 8 and moisture tester 9, on described moisture tester 9, be also connected with the second device for drying and filtering 10.
It should be noted that described the first expansion valve 7 and the second expansion valve 5 are heating power expansion valve or electric expansion valve.
It should be noted that described the first device for drying and filtering 8 and inner physical absorption drier and the chemisorbed drier of adopting of the second device for drying and filtering 10.
Double-source heat pump of the present utility model can, according to thermal source situation, if moisture tester excess moisture is set, by the second device for drying and filtering, if moisture is few, directly be connected with triple valve.The low-temperature evaporation that choice for use water source or air-source are cold-producing medium provides heat, flexible, can be according to the situation of ambient air temperature, give full play under the high energy efficiency of water resource heat pump and the low environment temperature of air heat pump still can maintaining heat pump work advantage.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
