By the Optimized Matching combination of aforementioned four subsystem, controller plc Intelligent adjustment, the workflow of the present invention is such as
Under:
(1) basic energy level mode of operation
When drying materials technique just starts, and high-temperature heat pump drying system does not need energy, temperature and humidity regulation, can be adopted this
Mode of operation.The flow process that Temperature and Humidity Control adjusts subsystem is: controller 9-2 is according to temperature sensor 9-3 and humidity sensor
The information of 9-4 input, opens air-cooled condenser blower fan 3-1, wind-cooled evaporator blower fan 4-1, and is adjusted to maximum wind velocity, closes energy
Regulating valve 9-1, hydrofuge exhaust fan 19, fresh-air fan 20 and electric heater 22.The flow process of high temperature heat pump subsystem is: pressure of inspiration(Pi)
Force regulating valve 12 and septum valve 13 standard-sized sheet, liquid injection valve 10 and differential regulating valve 14 are closed, the HTHP that compressor is discharged
The air-cooled condenser 3 that entered by oil eliminator 5 in casing 15 of refrigerant vapour discharge heat and become the supercooling of high pressure or full
The liquid refrigerant of sum, then in turn through septum valve 13, reservoir 6, device for drying and filtering 7, liquid-sighting glass 8, subcooler 11
Enter throttling arrangement 2, the liquid refrigerant of supercooling is changed into the gas-liquid two-phase of low-temp low-pressure after the flow restriction control of throttling arrangement 2
Cold-producing medium, is entered the superheated refrigerant steam being changed into low pressure after wind-cooled evaporator 4 absorbs heat, is then adjusted by pressure of inspiration(Pi)
Valve 12 enters compressor 1 and carries out next cyclic process.Baking room subsystem flow process is: the air in casing 15 is through air-cooled condensation
After device 3 absorbs heat intensification, enter storeroom through electric heater 22, after the material on the air heated material car 18 of high temperature,
Discharge heat cooling, absorb the moisture of material simultaneously, humidity increases, be then passed through the return airway of return air dividing plate 17 upside
Enter air-cooled condenser 3 and enter subsequent cycle.
(2) adjust energy level mode of operation
A, air-breathing throttling energy adjustment
When summer, outdoor temperature was higher, compressor 1 pressure of inspiration(Pi) is too high, motor load can be caused excessive, now air-breathing
Pressure-regulating valve 12 controls the pressure of inspiration(Pi) of compressor 1 according to downstream pressure (i.e. suction pressure of compressor), when pressure of inspiration(Pi) liter
Gao Shi, pressure of inspiration(Pi) regulating valve 12 turns down, and makes the refrigerant superheat steam throttling that wind-cooled evaporator 4 exports, with relatively low air-breathing
Pressure enters compressor.Other workflows are identical with basic energy level mode of operation.
B, Liquid injection cooling energy adjustment
When winter outdoor temperature is relatively low, and evaporating pressure and evaporating temperature are relatively low, or in drying materials technical process, condensation
When pressure and condensation temperature are too high, or when causing the degree of superheat excessive during energy adjustment, compressor 1 delivery temperature may be caused
Too high, liquid injection valve 10 can be adjusted the spouting liquid before entering pressure of inspiration(Pi) regulating valve 12, reduce according to the delivery temperature of compressor 1
The suction superheat of compressor, prevents compressor 1 excessive discharge temperature, meanwhile, in order to prevent the liquid refrigeration before throttling arrangement 2
Agent shwoot, through the gas-liquid two-phase cold-producing medium of liquid injection valve 10 throttling, first passes through subcooler 11, absorbs a part of liquid refrigerant
Before entering back into pressure of inspiration(Pi) regulating valve 12 after heat, this ensure that the degree of supercooling of cold-producing medium before throttling arrangement 2, improve evaporimeter
Refrigerating effect per unit swept volume and compressor efficiency.Other workflows are identical with basic energy level mode of operation.
C, hot-gas bypass energy adjustment
When, in drying materials technical process, when the temperature rise of storeroom is too fast, controller 9-2 is defeated according to temperature sensor 9-3
The information entering, opens capacity adjusting valve 9-1, and the refrigerant vapour part bypass of the HTHP that compressor 1 is discharged passes through energy
Adjustable valve 9-1, enters compressor air suction mouth after reducing pressure by regulating flow, reduces the thermal discharge of air-cooled condenser 3 it is therefore prevented that compressor
Run under 1 relatively low pressure of inspiration(Pi).Other workflows are identical with basic energy level mode of operation.
D, condenser reflux method energy adjustment
When winter outdoor temperature is very low, when high temperature heat pump system just starts, when condensing pressure is too low, before throttling arrangement 2
Pressure reduction is too little afterwards, and feed flow is short of power it is impossible to provide enough liquid supply rates to wind-cooled evaporator 4, by adjusting air-cooled condenser
When blower fan 3-1, wind-cooled evaporator blower fan 4-1 still do not have effect, this control method can be adopted.After start, septum valve 13 is closed,
Differential regulating valve 14 is opened, and compressor 1 is vented a part and is bypassed to reservoir 6, make pressure rise in reservoir 6.Work as condensation
Pressure rise to septum valve 13 unlatching value above when, septum valve 13 is slightly opened, and with the rising of storeroom temperature, ties up
When holding normal condensing pressure balance, the aperture of septum valve 13 increases to standard-sized sheet, and the aperture of differential regulating valve 14 diminishes to complete
Close, heat pump refrigerant walks normal circulation path.Other workflows are identical with basic energy level mode of operation.
E, damp and hot recovery operation pattern
When, in drying materials technical process, when storeroom humidity is excessive, controller 9-2 inputs according to humidity sensor 9-4
Information, open hydrofuge exhaust fan 19, fresh-air fan 20, a part of hot and humid storeroom air draft is through hydrofuge thermal wind exhausting
Machine 19 arranges outdoor, the fresh air of part outdoor low temperature and low humidity after entering wet heat recovering heat exchanger 23 air draft side release heat cooling
After fresh air screen pack 21 enters after wet heat recovering heat exchanger 23 fresh air side absorption heat heats up, enter through fresh-air fan 20
Casing 15, reduces the humidity of storeroom.Other workflows are identical with basic energy level mode of operation.
F, auxiliary electrical heater energy adjustment
When, in drying materials technical process, the temperature rise rate of storeroom is excessively slow, the high temperature heat pump unit energy adjustment of itself
When being not met by requiring, the information that controller 9-2 inputs according to temperature sensor 9-3, open electric heater 22, to through wind
The air of cool condenser 3 carries out reheating, for meeting the requirement of the temperature rise rate of storeroom.Other workflows with basic
Energy level mode of operation is identical.
