5.3) if the water temperature of water tank higher than set output temperature, and without forcing water request, postpone to supply water, running water pipe water inlet is simultaneously supplied water Water in Water Tank temperature drop to design temperature, when as reached the water level upper limit in water inlet temperature-fall period middle water level, temperature does not drop to design temperature, supply water immediately; If there is the request of supplying water of forcing, no matter in what temperature all supply water immediately;
6) judge the hydraulic pressure of radiator drain, if the pressure that is less than setting frequency converter raising frequency control constant voltage water pump by boost in pressure to setting value, if the pressure of supply water that is greater than setting frequency converter frequency reducing control constant voltage water pump by Pressure Drop to setting value.
Particularly, in above-mentioned steps 2) in sampling cistern water level, refer to that level sensor measures automatically.In step 3) in operation be to realize by the electric valve of automatic control.In step 4) in, if need to dehumidify separately, can compressor 33 be rear that compressor 33 is carried out to intermittent on off control starting, so that the heat exchange on evaporimeter 31 surfaces is intermittently carried out, can make so airborne a part of steam condensation is aqueous water, reduce air humidity, can also avoid temperature to reduce amplitude simultaneously excessive.The time interval of compressor 33 intermittent starts is longer, temperature reduce more not obvious, but also variation correspondingly of effect on moisture extraction; The time interval is shorter, and cooling-down effect and effect on moisture extraction all can improve.In actual use, the start and stop interval that need to debug compressor 33 according to on-the-spot air humidity with to the requirement of dehumidifying, to obtain a suitable effect on moisture extraction.If need cooling or cooling and dehumidifying carry out simultaneously, directly make compressor 33 keeps always turn round both can, until reach suitable temperature.In step 5.1) in, to heated speed determine according to the water in water tank 4 described time delay, firing rate is faster, and delay time is shorter, on the contrary delay time is longer.Because the parameter such as water temperature, the caliber of outlet pipe 44 of the water level in performance, the water tank 4 of the heat exchanger effectiveness of humiture, evaporimeter 31 and the condenser 32 of the useless damp-heat air in environment, compressor 33 and the water yield, running water all has impact to the firing rate of the water in water tank 4, therefore, this delay time needs could determine optimal values after the debugging of ground on the scene.
It will be appreciated that, the related determining step of temperature, humidity and pressure is all being carried out at any time in the running of whole system in said method, instead of once after judgement, just stop.The judgement of continuation like this, its benefit is to detect in time that the operating parameters of system changes, and control module is responded in time, thereby makes the water that water tank 4 is exported can keep water temperature, hydraulic pressure approximately constant.Any in employing PLC controller, singlechip controller or computerized control system can be by programming to meet this technical requirement of carrying out at any time parameter judgement as control module.
Through measuring and calculating, the system and method for the present embodiment is combined with following effect: the above-mentioned recuperation of heat unit 3 required power consumption of working is about 1/3rd to 1/5th of heat energy that evaporimeter 31 absorbs, and Optimization Work point absorbs 1/4th left and right of heat about evaporimeter; Described useless damp-heat air source is steam drying machine 1, and the temperature range of the useless hot and humid gas of its discharge is at 70～90 degrees Celsius, and the recyclable scope of the heat of recuperation of heat unit 3 contains this temperature range, and Optimization Work o'clock is corresponding to the damp-heat air of 80 degrees Celsius.The hot water scope that washing machine 2 uses is greatly about 30～60 degrees Celsius, optimum temperature is at 55 degrees Celsius, running water temperature before heating is generally lower than room temperature, and common is 10～25 degrees Celsius, and the maximum temperature after condenser 32 heating can be elevated to more than 60 degrees Celsius.According to actual using amount of hot water, remain on best 55 degrees Celsius by the parameters such as the design temperature of selection control system and the specification of compressor 33 water temperature that just can make easily to supply water.The reference data of relevant energy exchange is as follows: the ratio enthalpy of vaporization of every kilogram of saturated vapor: 2675.71kJ/kg; Specific heat of water holds: 4.186kJ/ (kg. DEG C); It is 766.48kW that 1000 kilograms of saturated steam phase transformings are cooled to 80 degrees Celsius of energy that discharge after for the aqueous water of 100 degrees Celsius again.
Disclosed is above only preferably specific embodiment of the present invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
