Combined by the Optimized Matching of above-mentioned four subsystems, controller PLC Intelligent adjustment, workflow of the present invention is as follows:
(1) basic energy level mode of operation
When drying materials technique just starts, when high-temperature heat pump drying system does not need energy, temperature and humidity regulation, this mode of operation can be adopted.The flow process of Temperature and Humidity Control adjustment subsystem is: the information that controller 9-2 inputs according to temperature sensor 9-3 and humidity sensor 9-4, open air-cooled condenser blower fan 3-1, wind-cooled evaporator blower fan 4-1, and be adjusted to maximum wind velocity, close capacity adjusting valve 9-1, hydrofuge exhaust fan 19, new wind blower fan 20 and electric heater 22.The flow process of high temperature heat pump subsystem is: pressure of inspiration(Pi) control valve 12 and septum valve 13 standard-sized sheet, liquid injection valve 10 and differential control valve 14 are closed, the refrigerant vapour of the HTHP that compressor is discharged becomes the cold or saturated liquid refrigerant of the mistake of high pressure by air-cooled condenser 3 release heat that oil eliminator 5 enters in casing 15, then successively through septum valve 13, reservoir 6, device for drying and filtering 7, liquid-sighting glass 8, subcooler 11 enters throttling arrangement 2, cross the gas-liquid two-phase cold-producing medium that cold liquid refrigerant becomes low-temp low-pressure after the flow restriction control of throttling arrangement 2, enter the superheated refrigerant steam becoming low pressure after wind-cooled evaporator 4 absorbs heat, then enter compressor 1 by pressure of inspiration(Pi) control valve 12 and carry out next cyclic process.Baking room subsystem flow process is: the air in casing 15 absorbs after heat intensification through air-cooled condenser 3, storeroom is entered through electric heater 22, after material on the air heat materials vehicle 18 of high temperature, releases heat is lowered the temperature, the simultaneously stability moisture of material, humidity increases, and the return airway then on the upside of return air dividing plate 17 enters air-cooled condenser 3 and enters next circulation.
(2) energy level mode of operation is regulated
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 pressure of inspiration(Pi) control 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) raises, pressure of inspiration(Pi) control valve 12 turns down, and the refrigerant superheat steam throttling that wind-cooled evaporator 4 is exported, enters compressor with lower pressure of inspiration(Pi).Other workflows are identical with basic energy level mode of operation.
B, Liquid injection cooling energy adjustment
When winter outdoor temperature lower, evaporating pressure and evaporating temperature lower time, or in drying materials technical process, condensing pressure and condensation temperature too high time, or when causing the degree of superheat excessive in energy adjustment process, compressor 1 excessive discharge temperature may be caused, liquid injection valve 10 can according to the delivery temperature of compressor 1, regulate the spouting liquid before entering pressure of inspiration(Pi) control valve 12, reduce the suction superheat of compressor, prevent compressor 1 excessive discharge temperature, simultaneously, in order to prevent the liquid refrigerant shwoot before throttling arrangement 2, through the gas-liquid two-phase cold-producing medium of liquid injection valve 10 throttling, first by subcooler 11, before entering pressure of inspiration(Pi) control valve 12 again after absorbing the heat of a part of liquid refrigerant, this ensure that the degree of supercooling of cold-producing medium before throttling arrangement 2, improve refrigerating effect per unit swept volume and the compressor efficiency of evaporimeter.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, the information that controller 9-2 inputs according to temperature sensor 9-3, open capacity adjusting valve 9-1, the refrigerant vapour part bypass of the HTHP that compressor 1 is discharged is through capacity adjusting valve 9-1, enter compressor air suction mouth after reducing pressure by regulating flow, reduce the thermal discharge of air-cooled condenser 3, run under preventing the lower pressure of inspiration(Pi) of compressor 1.Other workflows are identical with basic energy level mode of operation.
D, condenser reflux method energy adjustment
When winter outdoor temperature very low, when high temperature heat pump system just starts, when condensing pressure is too low, before and after throttling arrangement 2, pressure reduction is too little, feed flow is short of power, cannot provide enough liquid supply rates to wind-cooled evaporator 4, by regulating air-cooled condenser blower fan 3-1, wind-cooled evaporator blower fan 4-1 is not when still having an effect, can adopt this control method.After start, septum valve 13 is closed, and differential pressure control valve 14 is opened, and compressor 1 is vented a part and is bypassed to reservoir 6, and pressure in reservoir 6 is raised.When condensing pressure be elevated to septum valve 13 unlatching value above time, septum valve 13 is slightly opened, along with the rising of storeroom temperature, when maintaining normal condensing pressure balance, the aperture of septum valve 13 increases to standard-sized sheet, the aperture of differential pressure control valve 14 diminishes to complete shut-down, and 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, the information that controller 9-2 inputs according to humidity sensor 9-4, open hydrofuge exhaust fan 19, new wind blower fan 20, a part of hot and humid storeroom air draft enters after the release heat cooling of wet heat recovering heat exchanger 23 air draft side through hydrofuge exhaust fan 19 and is discharged to outdoor, the new wind of the outdoor low temperature and low humidity of a part enters the new wind side draught of wet heat recovering heat exchanger 23 through new wind screen pack 21 and receives after after heat intensification, enter casing 15 through new wind blower fan 20, reduce 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, when the energy adjustment of high temperature heat pump unit itself can't meet the demands, the information that controller 9-2 inputs according to temperature sensor 9-3, open electric heater 22, post bake is carried out to the air through air-cooled condenser 3, for meeting the requirement of the temperature rise rate of storeroom.Other workflows are identical with basic energy level mode of operation.
