Description

technical field [0001] The invention relates to a system in the field of energy technology, in particular to a combined system of a fuel cell and an air source heat pump water heater. Background technique [0002] First of all, the proton exchange membrane fuel cell system is a power generation device that uses hydrogen as fuel and oxygen in the air as oxidant. Due to the electrochemical reaction mechanism of the fuel cell, it is not limited by the efficiency of the Carroll cycle. Therefore, proton The exchange membrane fuel cell stack has the characteristics of high efficiency and environmental friendliness. When the proton exchange membrane fuel cell system is working, the temperature of the exhaust air is usually around 40°C and has a flow rate of 1-2m / s. cause a waste of energy. Secondly, the air source heat pump water heater is a water heater system based on the heat pump cycle, which uses the evaporator to absorb heat energy from the ambient air, and releases the hea...

Problems solved by technology

"Its disadvantages are: firstly, the invention uses three capillaries connected in parallel to form a capillary group, and correspondingly uses three solenoid valves. Therefore, this design is bound to greatly increase the cost of the system, increase the difficulty of system control, and weaken the stability of the system. ;Secondly, the use of three capillary tubes does not essentially solve the characteristics of the system's evaporation temperature changing with the seasons. Therefore, the seasonal energy efficiency ratio of the compressor still fluctuates up and down. also has a greater impact; finally, the existence of the axial flow fan in the system further increases the cost of the system, the complexity of the control and the power consumption of the system
