The said air discharge side of a compression engine is connected with an inlet end of a condenser, an outlet end of the condenser is respectively connected with an inlet end of an electromagnetic valve and a second inlet end of the electromagnetic valve, an outlet end of the electromagnetic valve is connected with an inlet end of a manual expansion valve, a second outlet end of the electromagnetic valve is connected with an inlet end of a thermal expansion valve, the outlet end of the manual expansion valve and the outlet end of the thermal expansion valve are respectively connected with an inlet end of an air cooler, an outlet end of the air cooler is connected with an air absorption side of the compression engine. The system alters the present situation of no refrigeration after starting the engine in the system of single warehouse cold storage refrigeration when adopting the thermal expansion valve, increases the efficiency of refrigeration, and saves energy.
Description
Technical field
The present invention relates to a kind of single storehouse cold storage refrigerating system novel throttling mode, specifically a kind of heating power expansion valve
The throttle style being used alternatingly with hand expansion valve parallel connection.
Background technology
In the single storehouse cold storage refrigerating system using heating power expansion valve, control storehouse temperature frequently with start/stop of compressor mode:
Ku Wen reaches temperature controller lower limit, compressor shutdown；Ku Wen reaches the temperature controller upper limit, and compressor is started shooting.Work as Ku Wenda
To temperature controller lower limit, compressor shutdown, affected by heat transfer across wall amount, storehouse temperature raises, muffler temperature raises,
Temperature-sensitive bag temperature raises, and expansion valve opening increases, and liquid supply rate increases, and evaporating pressure increases, and evaporating temperature raises, even above storehouse
Temperature, when storehouse temperature rise to temperature controller lower limit, during compressor start, vaporizer does not play refrigeration, causes the effect of refrigeration system
Rate reduces, the serious waste of the energy.
Content of the invention
The present invention is directed to the deficiency of the single storehouse cold storage refrigerating system using heating power expansion valve, proposes a kind of heating power expansion valve
In parallel with hand expansion valve, allow single storehouse refrigeration system that both are used alternatingly.
The present invention is achieved through the following technical solutions：
A kind of single storehouse cold storage refrigerating system that heating power expansion valve and hand expansion valve are used alternatingly is it is characterised in that institute
State compressor air-discharging side to be connected with condenser inlet end, described condensator outlet end respectively with electromagnetic valve one entrance point and described
Electromagnetic valve two entrance point is connected, and described electromagnetic valve one port of export is connected with hand expansion valve entrance point, described electromagnetic valve two
The port of export is connected with heating power expansion valve entrance point, the described hand expansion valve port of export and the heating power expansion valve port of export respectively with cold
Fan inlet end is connected, and the described air-cooler port of export is connected with suction side.
Inventive refrigeration system has following technique effect：
Single storehouse cold storage refrigerating system that a kind of heating power expansion valve of the present invention and hand expansion valve are used alternatingly, storehouse temperature from
During the temperature controller upper limit drops to temperature controller lower limit, using hand expansion valve throttling；Change swollen using heating power
In single storehouse cold storage refrigerating system of swollen valve, the present situation do not freezed of starting shooting, improves refrigerating efficiency, energy saving.
Brief description
Fig. 1 is present configuration schematic diagram.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.It should be appreciated that it is described herein
Specific embodiment only in order to explain the present invention, be not intended to limit the present invention.
As shown in figure 1, described compressor 1 exhaust side is connected with condenser 2 entrance point, described condenser 2 port of export divides
It is not connected with electromagnetic valve 1 entrance point and described electromagnetic valve 24 entrance point, described electromagnetic valve 1 port of export is expanded with manual
Valve 5 entrance point is connected, and described electromagnetic valve 24 port of export is connected with heating power expansion valve 6 entrance point, described hand expansion valve 5
The port of export is connected with air-cooler 7 entrance point respectively with heating power expansion valve 6 port of export, described air-cooler 7 port of export and compressor 1
Suction side is connected.
When storehouse is lowered the temperature first, storehouse Wen Xiancong room temperature drops to the temperature controller upper limit, then drops to from the temperature controller upper limit
Temperature controller lower limit, compressor shutdown, stop providing cold to storehouse, affected by heat transfer across wall amount, storehouse temperature liter
Height, reaches the temperature controller upper limit, and compressor is started shooting, and continues to provide cold to storehouse.
When storehouse is lowered the temperature first, during Ku Wen drops to the temperature controller upper limit from room temperature, described electromagnetic valve 1 cuts out,
Described electromagnetic valve 24 is opened, using heating power expansion valve throttling；Drop to temperature controller lower limit in storehouse temperature from the temperature controller upper limit
During, described electromagnetic valve 3 one is opened, and described electromagnetic valve 24 cuts out, using hand expansion valve throttling.
When storehouse opens the door or stocks up, amount of heat enters storehouse, and storehouse temperature raises, far above on temperature controller
Limit, this temperature-fall period, before storehouse temperature reaches the temperature controller upper limit, described electromagnetic valve 1 cuts out, described electromagnetic valve two
4 unlatchings, using heating power expansion valve throttling.
The above is only the preferred embodiment of the present invention it is noted that common skill for the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also should be regarded as protection scope of the present invention.
