Background technique
Low temperature changes in temperature dual-purpose type net for air-source heat pump units at present, under normal circumstances, coolant quantity needed for cooling condition are big, and
Coolant quantity needed for heating condition is small, but the both cooling and heating type unit of two kinds of functions of a system can only be filled by a standard
Coolant quantity, this results in unit refrigerant when in different operating conditions and distributes unbalanced problem, especially in heating peak load work
When condition (21 degree of dry bulb), excessive refrigerant also will cause system high pressure protection in system.Therefore needing to provide a kind of device can
Coolant quantity of the active balance low temperature changes in temperature dual-purpose type net for air-source heat pump units under different operating conditions.
The utility model of the prior art such as Publication No. CN202195629U discloses a kind of refrigerant of heat-pump hot-water unit
Balancing device constitutes compressor, double pipe heat exchanger, device for drying and filtering, compensator, the heating power of circulation loop including being linked in sequence
Expansion valve and fin-tube heat exchanger, gas-liquid separator increase compensator between device for drying and filtering and thermal expansion valve gear,
Excessive refrigerant can be temporarily stored, prevents refrigerant from flowing back in compressor start, caused to flow back into compressor, destroy system
Unite component, also avoid because refrigerant excessively caused by system high voltage protective.But it can not be supervised in time when system coolant quantity is on the low side
Police is observed and predicted, it is poor to will cause cooling system effect, or even unit can be damaged.
Utility model content
The purpose of this utility model is to provide one kind to be used for low temperature changes in temperature dual-purpose type air source heat pump refrigerant balancing device,
With the refrigerant balancing device that solves existing heat pump unit mentioned above in the background art, that there are system coolant quantities is on the high side or on the low side
When, it can not balance in time or monitoring, alarming, the problem of it is poor to will cause cooling system effect, or even unit can be damaged.
To achieve the above object, the utility model provides the following technical solutions:
One kind being used for low temperature changes in temperature dual-purpose type air source heat pump refrigerant balancing device, including is linked in sequence and constitutes circulation loop
Compressor, water-side heat, economizer, electric expansion valve and finned heat exchanger, wherein economizer is connect with Compressor Pipes,
Pipeline connects compensator between water-side heat and economizer；Setting pressure sensor at fluorine mouth is filled in finned heat exchanger,
And it is electrically connected with warning device.
Preferably, compensator is pressure balancing tank, is incorporated in the coolant system of air source heat pump, is connected by pipeline connection
Place is equipped with ring structure.
Preferably, the installation hook with screw hole is provided on compensator.
Compared with prior art, the utility model has the beneficial effects that
The utility model connects compensator between water-side heat and economizer, can refrigerant in active balance system, keep away
It is excessive to exempt from coolant quantity in system, and system high pressure is caused to protect；In addition setting pressure sensing at fluorine mouth is filled in finned heat exchanger
It is simultaneously electrically connected by device with warning device, can monitor whether refrigerant is sufficient in system and carries out warning reminding in time.This is practical
Novel refrigerant balance device structure is simple, can refrigerant in active balance system, system coolant quantity can also be monitored in time, in advance in advance
It is anti-, it is ensured that the refrigeration effect and operational safety of heat pump unit.
Detailed description of the invention
Fig. 1 is that the principal diagram of specific embodiment in the utility model is intended to；
Fig. 2 is compensator enlarged drawing in the utility model；
Fig. 3 is compensator side view in the utility model；
Fig. 4 is that compensator is mounted on position view in heat pump unit in the utility model；
Appended drawing reference: 1- compensator, 2- water-side heat, 3- economizer, 4- electric expansion valve, 5- finned heat exchanger, 6-
Compressor.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1 to Figure 3, shown, one kind being used for low temperature changes in temperature dual-purpose type air source heat pump refrigerant balancing device, packet
It includes to be linked in sequence and constitutes compressor 6, water-side heat 2, economizer 3, electric expansion valve 4 and the finned heat exchanger 5 of circulation loop,
Wherein economizer 3 is connect with 6 pipeline of compressor, passes through the pipeline connection compensator 1 between water-side heat 2 and economizer 3；?
Filling at fluorine mouth for finned heat exchanger is arranged pressure sensor and is electrically connected with warning device, realizes air source heat pump with this
Refrigerant balance.
Compensator 1 is hung in heat pump unit by installation, and is spirally connected reinforcing with screw, is protected after making the installation of compensator 1
Maintain an equal level steady, avoids inclination from installing or shake the influence to 1 internal pressure of compensator, as shown in Figure 4.Compensator 1 is connected by pipeline
It connects on the refrigeration system route between water-side heat 2 and economizer 3, place is sealed using ring structure in junction
Reason.
When just starting compressor 6, electric expansion valve 4 has little time to adjust, and compensator 1 temporarily stores excessive refrigerant, prevents
Only refrigerant return causes system high pressure to protect；When operating normally, compensator 1 is supplemented according to the size of system pressure for system
Or storage refrigerant, optimize the pressure balancing system of heat pump unit.In addition pressure biography is set in filling at fluorine mouth for finned heat exchanger 5
Sensor is simultaneously electrically connected with warning device, when pressure sensor detects that the pressure at fluorine mouth of filling of finned heat exchanger 5 is less than system
When setting value, illustrate that system pressure is low, cold medium shortage, pressure sensor signal can be transmitted to warning device carry out alarm mention
It wakes up, user injects refrigerant into compensator 1 or system after being connected to signal, works normally heat pump unit, prevents heat pump machine
Group refrigeration effect due to lacking refrigerant is bad, or even damage machine group parts, influence unit operational safety and so on.
