Distributed water-steam-cold-heat-electricity combined supply device and method

Abstract

The invention discloses a distributed water-steam-cold-heat-electricity combined supply device and method. The device comprises a cooling and heating module, a power supply module, a humidifying module, a power consumption module and a water consumption module; operation electricity is provided by a fuel cell stack, when heating is performed, part of circulating water directly enters an outdoor heat exchanger, the other part of the circulating water enters a cell cooling loop before entering the outdoor heat exchanger and further enters the outdoor heat exchanger to exchange heat with a compressor loop and circulate, the stack can be cooled and the circulating water can be preheated while the heating target is realized, the work of the compressor is reduced while the temperature of the stack is reduced, and the operation efficiency of the stack and the whole device is improved; when cooling is performed, part, flowing out and then flowing in a cooling tower, of the outdoor circulating water directly enters the outdoor heat exchanger, the other part enters the cell cooling loop, further flows into a cooling tower water tank again and flows out for circulation, the stack can be cooled while the cooling target is realized, and the operation efficiency of the stack is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a distributed water vapor combined cooling, heating and power supply device and method. Background technique [0002] With people's higher and higher requirements for living comfort, cold, heat, electricity, water, and humidity have become the basic needs of people's lives. unbalanced. In order to meet the requirements of the power load, the power sector has to generate power according to the maximum load, which also leads to excess and waste of power to a certain extent, and at the same time has to perform power limit management during the peak period of power consumption. Especially in recent years, my country's "power rationing" problem and the world's "blackout" accidents have appeared more and more frequently in people's field of vision, which is very inconsistent with the concept of sustainable development, energy saving and consumption reduction advocated by my c...
