5.3) if the water temperature of water tank is higher than the output temperature of setting; And do not have the request of the water of pressure, then postpone to supply water, running water pipe water inlet simultaneously is with supplying water behind tank water temperature drop to the design temperature; When temperature does not drop to design temperature as reaching the water level upper limit in water inlet temperature-fall period middle water level, then supply water immediately; If the request of exist to force supplying water then all supply water immediately no matter be in what temperature;
6) judge the hydraulic pressure of radiator drain, if less than the pressure of setting then frequency converter raising frequency control constant voltage water pump with boost in pressure to setting value, if greater than the pressure of supply water of setting then frequency converter frequency reducing control constant voltage water pump pressure is reduced to setting value.
Particularly, in above-mentioned steps 2) in the sampling cistern water level, be meant that level sensor measures automatically.Operation in step 3) is to realize through the electric valve of automatic control.In step 4); Dehumidify separately if desired; Then can after starting compressor 33, carry out intermittent start and stop control,, can make airborne a part of steam be condensed into aqueous water like this so that the heat exchanges on evaporimeter 31 surfaces are intermittently carried out to compressor 33; Reduce air humidity, it is excessive to avoid temperature to reduce amplitude simultaneously.The time interval of compressor 33 intermittent starts is long more, then temperature reduce not obvious more, but also variation correspondingly of effect on moisture extraction; The time interval is short more, and then cooling-down effect and effect on moisture extraction all can improve.In actual the use, need be according to the air humidity at scene and the start and stop interval that compressor 33 is debugged in the requirement of dehumidifying, to obtain a suitable effect on moisture extraction.If need cooling or cooling and dehumidifying to carry out simultaneously, then directly make compressor 33 both keeps turning round always can, till reaching suitable temperature.In step 5.1) in, will confirm that according to the heated speed of the water in the water tank 4 firing rate is fast more said time delay, then delay time is short more, on the contrary delay time is long more.Because the water temperature of the heat exchanger effectiveness of humiture, evaporimeter 31 and the condenser 32 of the useless damp-heat air in the environment, performance, the water level in the water tank 4 and the water yield of compressor 33, running water, the parameters such as caliber of outlet pipe 44 are all influential to the firing rate of the water in the water tank 4; Therefore, this delay time needs could confirm optimal values after the debugging of ground on the scene.
It will be appreciated that the determining step to temperature, humidity and pressure related in said method is all carrying out at any time in the running of whole system, rather than just stop after once judging.The judgement of continuation like this, its benefit are can in time detect operating each parameter of system to change, and control module is in time responded, thereby make the water of water tank 4 outputs can keep water temperature, hydraulic pressure approximately constant.In employing PLC controller, singlechip controller or the computerized control system any can satisfy this specification requirement that parameter is judged of carrying out at any time through programming as control module.
Through measuring and calculating; The system and method for present embodiment is used in combination following effect: the required power consumption of above-mentioned recuperation of heat unit 3 work is about 1/3rd to 1/5th of heat energy that evaporimeter 31 absorbed, and optimization work point is about about 1/4th of evaporimeter absorption heat; Described useless damp-heat air source is a steam drying machine 1, and the temperature range of the useless hot and humid gas of its discharging is at 70～90 degrees centigrade, and the hot recyclable scope of recuperation of heat unit 3 contains this temperature range, and optimization work o'clock is corresponding to 80 degrees centigrade damp-heat air.Washing machine 2 employed hot water scopes are greatly about 30～60 degrees centigrade; Optimum temperature is at 55 degrees centigrade; Running water temperature before the heating generally is lower than room temperature, and common is 10～25 degrees centigrade, then can be elevated to more than 60 degrees centigrade through the maximum temperature after condenser 32 heating.According to the hot water consumption of reality, just can make the water supply water temperature remain on best 55 degrees centigrade easily through the design temperature of selection control system and the parameters such as specification of compressor 33.The reference data of relevant energy exchange is following: the ratio vapourization enthalpy of every kilogram of saturated vapor: 2675.71kJ/kg; Specific heat of water holds: 4.186kJ/ (kg. ℃); 1000 kilograms of saturated steam phase transformings are that to be cooled to 80 degrees centigrade of energy that discharged again behind 100 degrees centigrade the aqueous water be 766.48kW.
More than the disclosed more excellent specific embodiment of the present invention that is merely, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
