Technical field
The present invention relates to refrigeration technology field more particularly to a kind of refrigerant-cycle systems.
Background technique
Compressor set is the important component of refrigeration system, and the power of compressor set can not be into traditional refrigeration system
Row is adjusted, and is easy to appear the situation of supercooling or refrigeration work consumption deficiency, meanwhile, when compressor set breaks down, need to shut down dimension
It repairs, influences normal use.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, providing one kind can be according to need
Adjust the refrigerant-cycle systems of compressor set power.
The present invention is to be achieved by the following technical programs:
A kind of refrigerant-cycle systems characterized by comprising refrigerant storage tank, heat exchanger, compressor set, electronics
Expansion valve and condensation fan,
Coolant coil is equipped in the heat exchanger, refrigerant storage tank passes through inlet tube and liquid back pipe and coolant respectively
The both ends of coil pipe are connected to, and the liquid back pipe is equipped with sensor, are additionally provided with input pipe and efferent duct on heat exchanger,
The compressor set includes multiple compressors in parallel, and compressor passes through pipeline and condensation fan and refrigerant storage
Tank forms refrigerant cooling circuit, and the electric expansion valve is set to the pipeline that refrigerant flows to compressor from refrigerant storage tank
On.
Preferably, the sensor includes temperature sensor and pressure sensor.
The beneficial effects of the present invention are:
By the performance parameter for the refrigerant that sensor real-time reception flows back, the pressure of compressor set starting different number is triggered
Contracting machine, to change the operation power of compressor set as needed, can to avoid the waste of energy consumption or the deficiency of refrigeration work consumption, when
When wherein a compressor breaks down, it is only necessary to which one of shutdown maintenance failure, other compressors can still operate normally, simultaneously
A set of circulation line is shared in refrigeration compressor parallel-connection structure, effectively saves the usage amount of refrigerant, substantially saves freezing
The cost of agent.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the invention.
In figure: 1. refrigerant storage tanks, 2. heat exchangers, 3. compressors, 4. electric expansion valves, 5. condensation fans, 6. is cooling
Agent coil pipe, 7. inlet tubes, 8. liquid back pipes, 9. sensors, 10. input pipes, 11. efferent ducts.
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing and most
The present invention is described in further detail for good embodiment.
As shown, the present invention includes: refrigerant storage tank 1, heat exchanger 2, compressor set, electric expansion valve 4 and condensation
Blower 5,
Be equipped with coolant coil 6 in the heat exchanger, refrigerant storage tank pass through respectively inlet tube 7 and liquid back pipe 8 with it is cold
But the both ends connection of agent coil pipe, the liquid back pipe are equipped with sensor 9, are additionally provided with input pipe 10 and efferent duct 11 on heat exchanger,
Fluid to be cooled is flowed out through input pipe inflow heat exchanger and from efferent duct, and coolant through inlet tube enters heat exchanger and from liquid back pipe
Outflow, the heat of the refrigerant suction of low temperature fluid to be cooled increases refrigerant temperature in heat exchanger, fluid temperature to be cooled
Degree reduces, and the performance parameters such as the temperature of refrigerant of refrigerant storage tank are flowed back in sensor reception, and processor is according to performance parameter
It adjusts compressor set and runs power, when performance parameter is higher than setting value, triggering is increased into compressor start quantity, when performance is joined
When number is lower than setting value, triggering is reduced into compressor start quantity, to realize the dynamic adjustment of compressor horsepower, will not both be made
At the waste of energy consumption, the deficiency of refrigerating capacity will not be caused,
The compressor set includes the compressor 3 of multiple parallel connections, and compressor passes through pipeline and condenser and refrigerant storage
Tank forms refrigerant cooling circuit, and the electric expansion valve is set to the pipeline that refrigerant flows to compressor from refrigerant storage tank
On, processor records the runing time and downtime of each compressor, at regular intervals according to runing time to whole pressures
Contracting machine is ranked up, preferential to start the short compressor of runing time, and each downtime of compressor is not less than 3 minutes, and
The each run time is not less than 1 minute, to keep multiple compressor operating times more uniform, when respective compressive machine being avoided to run
Between it is too long cause to break down, while high frequent start and stop being avoided to lead to compressor damage,
The sensor is used to obtain refrigerant and completes the performance information after refrigeration, processor receptivity information and basis
Performance information adjusts compressor start quantity and controls the switch of condensation fan.
Preferably, the sensor includes temperature sensor and pressure sensor, for collecting the pressure and temperature of refrigerant
Degree.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
