The working principle of the invention:
(1), when equipment works, when the feed flow temperature that feed flow temperature sensor 6 detects is lower than set temperature, illustrate equipment
Real-time refrigerating capacity is greater than load calorific value, and controller is first begin to carry out electrodeless decompression speed to condensation fan 16, until feed flow
Temperature is stabilized within the scope of set temperature；When the wind speed of condensation fan 16 is adjusted to deep low gear, feed flow temperature is remained below
Set temperature, controller control hot gas bypass solenoid valve 15 and open, the high-temperature high-pressure refrigerant gas that compressor 12 is discharged is drawn
Enter into evaporator 10, actively reduces the refrigerant flow for passing through air-cooled condenser 13, that is, the refrigeration of refrigeration unit is greatly reduced
Amount, equipment cooling capacity is minimum under this state；If the feed flow temperature bottom out that feed flow temperature sensor 6 detects at this time, and
Continue to go up after reaching desired temperature, controller carries out wind speed to condensation fan 16 and adjusts, until feed flow temperature sensor 6 is examined
The feed flow temperature measured is stabilized within the scope of set temperature；When condensation fan 16 wind speed restore maximum wind velocity when refrigerating capacity still
Deficiency, controller close hot gas bypass solenoid valve 15, and refrigeration unit restores maximum refrigerating capacity.Actual tests statistics indicate that,
The hot gas bypass solenoid valve 15 of equal calibers cooperates condensation fan 16 to adjust the speed, and maximum discharging quantity can reach the 70% of rated cooling capacity,
Meet in most cases to the use demand of equipment.
(2), when the set temperature of controller is greater than environment temperature, controller starts electric heater 17 to refrigerating agent solution
Refrigerating medium in case 3 is preheated, and after being preheating to set temperature, controller starts circulating pump 4 and starts to work, at this time electric heater
17 close；When load heat enters refrigerating medium, when feed flow constant temperature being caused to rise and be more than set temperature, refrigeration unit starts
Work.
(3), when refrigeration unit works, if flow setting value is less than the metered flow of circulating pump 4, controller can basis time
The feed flow flow parameter that flow meters 22 acquire carries out real-time PID adjusting to distributing T-pipe regulating valve 18, will flow into refrigerating
Refrigerating medium a part of agent supply opening 5 bypasses Huis liquid pipeline 2, and another part is exported and is conveyed to negative from refrigerating medium supply opening 5
It carries and uses, stablize within setting range of flow until returning the feed flow flow parameter that flow meters 22 acquire.The control method can
To realize the full dose process control for flow quantity 0-100%, and in the 30-100% range of 18 inlet flow rate of distributing T-pipe regulating valve
Interior, flow control accuracy can achieve 1%.If required bypass flow is the 0-30% range of 18 inlet flow rate of distributing T-pipe regulating valve
Interior, the adjusting of 18 spool of distributing T-pipe regulating valve and actual flow variation Linear Comparison error are larger, and degree of regulation is limited；At this time
It can be by manually adjusting the aperture of bypass regulator valve 19, default a part of refrigerating medium of bypass returns to refrigerating medium liquor box 3, reduces
The inlet flow rate of distributing T-pipe regulating valve 18, then PID shunt regulating is carried out to for flow quantity.Pass through the default knot of bypass regulator valve 19
The scheme that the automatic PID of shunting valve 19 is adjusted is closed, this equipment can be realized in the range ability of the 10-100% of metered flow
It is accurate to adjust, it controls precision and range is all substantially better than method for controlling frequency conversion.
(4), fractional load needs relatively high feed flow back pressure, and controller is by opening the backpressure regulation on liquid back pipe road 2
Back pressure is adjusted in valve 21, and pressure oscillation will lead to the variation of flow, therefore distributing T-pipe is adjusted after backpressure regulation
The meeting automatic work of valve 18, adjusts feed flow stability of flow within the set range.
(5), refrigeration unit has double cold source modes, when environment temperature is lower than 15 DEG C of controller set temperature or more, control
Device control electric T-shaped valve 20 processed carries out outlet conversion, directly switches refrigerating medium and flows to air-cooled condenser 13, air-cooled at this time cold
The condensation fan 16 of condenser 13 works, and controller controls evaporator 10 and compressor 12 is closed, and refrigerating medium directly passes through condensating wind
Machine 16 carries out forced air cooling cooling, and much smaller than compression refrigeration mode, energy-saving effect is aobvious for refrigeration unit power consumption under forced air cooling mode
It writes.
