Description
Technical field
The present invention relates to a kind of air-conditioning system, particularly relate to a kind of domestic air-conditioning system of fuel cell.
Background technology
Conventional domestic air conditioning is mainly by panel beating module compositions such as compressor, condenser, evaporimeter, choke valve, outdoor condensation fan, indoor fan, electric-controlled plate and shells.
Air conditioner refrigerating principle, after air-conditioner energising, the low-pressure steam of refrigeration system inner refrigerant (that generally use now is freon R22) is sucked also and drains into condenser after boil down to high steam by compressor.The outdoor air that simultaneously aerofoil fan the sucks condenser of flowing through, takes away cold-producing medium liberated heat, makes high pressure refrigerant vapor be condensed into highly pressurised liquid.Highly pressurised liquid sprays into evaporimeter after filter, throttle mechanism, and evaporates under corresponding low pressure, draws heat around.Simultaneously axial-flow fan constantly enters between the fin of evaporimeter air to carry out heat exchange, and the air turning cold after heat release is sent to indoor.So room air constantly circulates, and reaches the object that reduces temperature.
Air-conditioning heating operation principle, it is to utilize the compression condensation device of refrigeration system to heat room air that heat pump heats.Air-conditioner when refrigeration work, low pressure refrigerant liquid evaporation endothermic and high-temperature high-pressure refrigerant heat release condensation in condenser in evaporimeter.It is by electromagnetic switch that heat pump heats, by the suction position of trachea exchange of refrigeration system.Originally the indoor coil of refrigeration work evaporimeter becomes the condenser while heating, and refrigeration system, in outdoor heat absorption to indoor heat release, realizes the object heating like this.
Freon refrigeration air-conditioning has several large disadvantages:
1, air-conditioning is high consumer products, and air-conditioning a large amount of universal cause seasonality, period electricity shortage.
2, air-conditioning refrigeration system cold-producing medium used has destruction to atmospheric ozone layer; Cause global greenhouse effect aggravation.
3, air-conditioning is used throughout the year, causes growing some bacteriums above air conditioner indoor unit evaporator, and people is had to certain influence;
When 4, using air conditioner refrigerating, can cause the relative air humidity in room to reduce, easily make people feel mouth parched and tongue scorched;
Fuel cell be a kind of without burning directly in electrochemical reaction mode, the chemical energy of fuel is changed into the TRT of electric energy, be the new technology that a high efficiency is utilized the energy and don't contaminated environment.Fuel cell has polytype, by the different classification of the electrolyte using, mainly contain phosphoric acid type fuel cell (PAFC), molten carbonate fuel cell (MCFC), SOFC (SOFC), Proton Exchange Membrane Fuel Cells (PEMFC) and alkaline fuel cell (AFC).Fuel cell is considered to the generation technology of new generation after thermal power generation, hydroelectric generation, solar electrical energy generation and nuclear electric power generation, has the incomparable superiority of other generation mode:
(1) efficiency is high.Fuel cell is converted into electric energy by chemical energy, do not relate to heat engine process, power conversion is not subject to the restriction of Carnot cycle, its theoretical thermoelectric conversion efficiency can reach 85% ~ 90%, but because battery is subject to the restriction of various polarization when working, the actual power efficiency of each types of fuel cells is all in 40% ~ 60% scope at present, if realize cogeneration, overall thermal efficiency can reach more than 80%.
(2) environmental friendliness.Fuel cell discharges NO hardly
xand SO
x, greenhouse gases CO
2discharge capacity also than thermal power generation, reduce 40% ~ 60%, alleviated the pollution to atmosphere; There is no drive disk assembly, during work, noise is extremely low, thereby can be directly arranged near user, thereby reduces transmission cost and transmission loss.The environment friendly of fuel cell is the main cause that makes it have extremely strong vitality and long term growth potentiality.
(3) reliability is high.Compare with combustion gas turbine or internal combustion engine, fuel cell does not have mechanical transmission component, thereby system is more safe and reliable, can not cause because drive disk assembly is malfunctioning serious accident.
