Description
Technical field
The utility model is related to household appliance technical field, especially, is related to a kind of Teat pump boiler outdoor unit.
Background technology
Heat pump can utilize the heat energy in air, thus can be used in water heater or air-conditioner as the thermal source of energy-conservation.So
And, the hot water supply pattern or the quick heating in relatively low (e.g., from about -15 DEG C) temperature in higher temperature (e.g., from about 60 DEG C)
When running Teat pump boiler under pattern, the evaporating temperature of evaporimeter is reduced.Therefore, if by refrigerant compression to predetermined pressure,
The temperature of the cold-producing medium then discharged from compressor will increase.Now, the overheat protective function of discharge refrigerant temperature is performed, with true
The reliability of compressor is protected, the capacity of compressor is thus reduced.This has resulted in water heater heating efficiency or supply hot water energy
The problem that power is reduced.
The content of the invention
Therefore, the purpose of this utility model is to provide a kind of Teat pump boiler outdoor unit, wherein, in compression process
Injection cold-producing medium, so as to improve heating efficiency at relatively low ambient temperatures.
For achieving the above object, the utility model provides a kind of Teat pump boiler outdoor unit, the Teat pump boiler
Outdoor unit include water heat exchanger, air heat exchanger, the first intermediate heat exchanger and compressor, the water heat exchanger,
Connected by pipeline between air heat exchanger, the first intermediate heat exchanger and compressor, on the pipeline four-way is provided with
Valve, for freezing and being changed between heating, is provided with first swollen between water heat exchanger and the first intermediate heat exchanger
The second expansion valve is provided between swollen valve, and the first intermediate heat exchanger and air heat exchanger, it is characterised in that in compression
Cold-producing medium filling line is provided between machine and the first Intermediate Heat Exchanger, inlet and the 3rd are provided with the filling line
Expansion valve, and the filling line is by the second intermediate heat exchanger of the setting on refrigerant line.
Preferably, water lines are additionally provided with the water heat exchanger, are connected with indoor unit.
Preferably, it is respectively arranged with temperature sensor at the two ends of the compressor.
Preferably, it is provided with temperature sensor below the air heat exchanger.
The utility model has the advantages that：
Teat pump boiler of the present utility model between compressor and Intermediate Heat Exchanger by introducing extra cold-producing medium note
Enter pipeline, and heat exchange is carried out with refrigerant line, so that in the case where outdoor environment temperature is relatively low, it is new by injection
Cold-producing medium and obtain heat, continue, stably heat exchange carried out to circulation line, transfer heat to water heat exchanger,
And then efficiently water is heated.Whole Teat pump boiler keeps high-effect.
In addition to objects, features and advantages described above, the utility model also has other purposes, feature and excellent
Point.Below with reference to figure, the utility model is described in further detail.
