Abstract
The utility model is related to a kind of refrigeration or heat pump and a kind of Condensing units, and the refrigeration or heat pump include compressor, condenser, throttling arrangement and evaporator, it is characterised in that：Check valve is provided with connecting pipe between the compressor and the condenser, bypass line is provided with the connecting pipe between the compressor and the check valve, bypass line connection low-pressure side, and it is provided with capillary on the bypass line.Refrigeration of the present utility model or heat pump, balance is reached the pressure before and after capillary makes compressor is shut down by, so as to make compressor be started shooting with less staring torque and starting current.
Description
Technical field
The utility model is related to refrigerating field, in particular to one kind refrigeration or heat pump and a kind of compression condensation machine
Group.
Background technology
Refrigerant migration during to prevent from shutting down, some refrigeration systems are provided with liquid pipe magnetic valve, and liquid pipe is first closed before shutting down
Magnetic valve, is shutting down after evacuation circulation is carried out to evaporator.But, the staring torque of compressor is very big during start, compressor
Starting current is very big.
Simultaneously for refrigeration system, setting liquid pipe magnetic valve can also prevent the heat of condenser side from entering when shutting down
Evaporator can make the pressure of evaporator quickly lower so as to subtract so as to increase the thermic load of refrigerating plant in start
Few power consumption.But it is same, although high-low pressure have been isolated by liquid pipe magnetic valve, the staring torque of compressor is very big during start.
Utility model content
The purpose of this utility model is to solve the above problems.
The technical solution of the utility model is as follows：
One kind refrigeration or heat pump, comprising compressor, condenser, throttling arrangement and evaporator, from compressor warp
The condenser to the refrigerant passage between the throttling arrangement is high-pressure side, from the throttling arrangement through the evaporator to institute
It is low-pressure side to state the refrigerant passage between compressor, it is characterised in that：Connection between the compressor and the condenser
Check valve is provided with pipeline, bypass line is provided with the connecting pipe between the compressor and the check valve, by this
Logical pipeline connection low-pressure side, and it is provided with capillary on the bypass line.
Further, it is additionally provided with filter on the bypass line.
Preferential, the bypass line connects the connecting pipe between the evaporator and the compressor.
Further, the throttling arrangement is electric expansion valve.
Further, it is provided with liquid pipe magnetic valve on the connecting pipeline between the condenser and the throttling arrangement.
A kind of Condensing units, comprising compressor and condenser, are provided with the suction connected with compressor air suction mouth
Air pipe, it is characterised in that：Check valve is provided with connecting pipe between the compressor and the condenser, described
Connecting pipe between compressor and the check valve is provided with bypass line, and the bypass line connects the suction line, and
Capillary is provided with the bypass line.
Further, it is additionally provided with filter on the bypass line.
Based on above-mentioned technical proposal, refrigeration of the present utility model or heat pump can not only set liquid pipe magnetic valve, rise
To its positive role, but compressor can be made to be started shooting with less staring torque simultaneously.
Brief description of the drawings
Fig. 1 is the theory of constitution schematic diagram of the utility model refrigeration or heat pump first embodiment.
Specific embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in figure 1, being the utility model refrigeration or the theory of constitution schematic diagram of heat pump first embodiment.Wherein,
Compressor 1, check valve 5, condenser 2, liquid pipe magnetic valve 8, heating power expansion valve 3, evaporator 4 are sequentially connected in series connection, in compressor 1
And also bypass has a pipeline on the connecting line between check valve 5, the bypass line sequentially passes through filter 7, capillary 6 and connects
Connect the air entry of compressor 1.
It should be noted that the resistance of capillary 6 should be as big as possible, so that by capillary 6 when system is normally run
Exhaust bypass amount is as far as possible small, but (protection compressor, prevents from frequently opening simultaneously as the downtime of compressor is at least 3 minutes
It is dynamic), then in 3 minutes after compressor shutdown, capillary 6 should be able to also make in compressor 1 to the connecting line of check valve 5
Pressure and low-pressure balance, so, check valve 5 is made as far as possible near compressor 1, to reduce the volume of pipeline between them.
Finally it should be noted that：Above example is merely to illustrate the technical solution of the utility model rather than it is limited
System, person of an ordinary skill in the technical field should be appreciated that and still specific embodiment of the present utility model can be repaiied
Change or equivalence replacement is carried out to some technical characteristics.So, without departing from the spirit of technical solutions of the utility model, all should
This is covered in the middle of the claimed technical scheme scope of the utility model.
