Summary of the invention
The objective of the invention is in order to overcome the weak point of above-mentioned prior art; Propose a kind of multifunctional heat pump water heating machine group that adopts and come method and the comprehensive utilization of energy system thereof that the application workshop moisture temperature is controlled; Native system can be on the basis that guarantees workshop moisture temperature control; Provide hot water to use, fully energy savings to the workshop.
The technical solution adopted for the present invention to solve the technical problems is: when utilizing the multifunctional heat pump water heating machine group to handle new wind, guaranteeing that new wind water capacity and wind pushing temperature reach under the situation of designing requirement, reclaim new wind-heat amount, produce hot water and supply user's use; Specifically comprise following several kinds of situation:
(1) is lower than the new wind of the air water capacity that requires in the workshop for its water capacity, utilizes water after the heating of multifunctional heat pump water heating machine group directly to contact it is carried out humidification with new wind;
(2) for the new wind of its water capacity greater than the air water capacity that requires in the workshop, the frozen water that utilizes the multifunctional heat pump water heating machine group to produce carries out cool-down dehumidification through Cooling and Dehumidifying Coil to little new wind;
(3) be lower than the new wind of the air themperature that requires in the workshop for temperature behind the humidification, utilize water after the heating of multifunctional heat pump water heating machine group to contact with new wind it is heated through heat exchange coil;
(4) for the new wind of its temperature greater than the air themperature that requires in the workshop, utilize frozen water that the multifunctional heat pump water heating machine group produces through Cooling and Dehumidifying Coil to trade wind lower the temperature (dehumidifying); Then humidification with heat, air-out is met the requirements.
In shipbuilding application workshop moisture temperature control method and comprehensive utilization of energy system thereof; The nucleus equipment that adopts the multifunctional heat pump water heating machine group to regulate as workshop moisture temperature, this multifunctional heat pump water heating machine group can realize: heat separately water, separately ice making water, heat water and frozen water simultaneously.The hot water that the multifunctional heat pump water heating machine group is produced focuses on earlier in the big attemperater, can be used as humidification then as required and uses hot water with hot water, the new wind of heating with hot water, workshop, has realized the comprehensive utilization of the energy.
The invention has the beneficial effects as follows: suit of the present invention has the workshop of air-conditioning system in industrial circle; Its application will make the workshop heat extraction that does not utilize as yet at present obtain good use; Therefore reducing using of industrial plant greatly can load; Have great importance for the energy-saving and cost-reducing of industrial enterprise, the synthesis energy saving effect is obvious.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
