Distributed air conditioning device and method

Abstract

The invention discloses a distributed air conditioning device and method. The device comprises a refrigeration and heating module, an energy supply module and a humidification module. During operating, all needed electric energy is provided by a fuel cell stack, meanwhile, products in the refrigeration and heating cyclic process are used for cooling the fuel cell stack, and products of stack operating can achieve the functions of defrosting and humidification. In the heating process, defrosting products of an outdoor heat exchanger flow into a stack cooling loop to cool the stack, waste products are fully utilized, and meanwhile the overall operating efficiency of the stack and the device are improved. In the refrigeration process, condensation products of an indoor heat exchanger flow into the stack cooling loop to cool the stack, and the operating efficiency of the stack is improved. In the defrosting process, heat needed for the outdoor heat exchanger is provided by products of a fuel cell, and equipment acting is reduced. In the humidification process, water and heat needed for the device are obtained in the products of the cell, and resource waste is reduced. The device can overall operate independently and stably, the basic requirements of distributed energy resources are met, and the beneficial effects of being efficient, saving energy, being clean and environment-friendly, having diversified functions and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a distributed air conditioning device and method. Background technique [0002] With people's higher and higher requirements for living comfort, a living environment with good temperature and humidity has become the basic demand of people's life. These demands have also led to a substantial increase in the electricity consumption of residents' air-conditioning equipment, which in turn has led to the shortage of power supply and demand in my country. balance. 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...
