Solar semiconductor refrigeration and air conditioning is based on solar photovoltaic effect, ie, by the light - electric - cold "way, and use the electricity generated by solar cell-driven semiconductor refrigeration device, in order to achieve a special cooling methods for heat transfer. Solar photovoltaic conversion of electrical energy not only with the thermoelectric refrigeration DC power supply model to match, solar light radiation and the cooling capacity needs have a good time matching. In addition, solar energy clean and green, resource-rich, inexhaustible, inexhaustible, and the solar and semiconductor environment-friendly common, therefore, solar semiconductor refrigeration and air solar water heater supplier can create high-quality green living space. This design is the use of Hainan's unique natural conditions, a low cost basis, solar semiconductor refrigeration and air conditioning test equipment design. The method has broad application prospects in Hainan as well as in tropical regions, one of the tasks of this topic is air-conditioning control system for solar semiconductor design.
    A solar semiconductor air-conditioning system constitutes
    Solar Semiconductor cooling system can be solar photovoltaic conversion devices, energy matching the five components of the NC, energy storage, semiconductor refrigeration equipment, systems and control devices.
    Sunshine, photovoltaic inverter sun shines on it convert light energy into electrical energy for air-conditioning system to provide the necessary energy source. This article photovoltaic inverter output power and air conditioning systems need electricity to have a good consistency, while the other auxiliary energy storage device, without sunlight or sunlight for photovoltaic inverter output electrical energy to be stored for later, thus ensuring the Solar Semiconductor air-conditioning system can run around the clock. NC matcher enable the solar array's output impedance and the equivalent load impedance match to make the entire system of energy transmission conversion is always at its best, at the same time the energy storage device overcharge, over discharge control.
    Semiconductor cooling and heating devices are usually composed by the multi-block thermopile or cooling unit, cold end and hot end of the installation of a cooling device. Need refrigeration, the cold side in the indoor heat-absorbing, in order to achieve the purpose of lowering the temperature refrigeration; the hot end is placed outside the ventilation and heat dissipation. In winter, the lower the ambient temperature heating is required, you can change by changing the power of positive and negative direction of the current through the thermopile, the thermopile cold junction becomes hot end to the indoor heat, while the the hot end into a cold-side absorbs heat to the surrounding environment, so as to achieve the purpose of heating and air conditioning.
    The system control device has two functions, first, to adjust the indoor temperature measurement and control the temperature of the cold end and hot end of the chilling plate thermal conductivity of ceramic surface. The second is to adjust the indoor humidity, to control a humidification device. The solar water heaters not only can be automated and intelligent, but also to provide the most comfortable environment for the interior.
    2 air-conditioning control system design
    Semiconductor cooling and heating device, cooling piece cold end and hot end of the thermal conductivity of ceramic chip coated the surface of the ideological and thermal grease to reduce contact resistance, thermal grease more than 60 ℃ to melt, so you need to keep abreast of the ceramic surface the temperature exceeds this temperature, you need to turn on the fan cooling. In addition, the regulation of the room temperature is set within a certain range (-10 ° C to 40 ° C), the user can adjust the temperature according to their own requirements, accuracy up to ± 0.5 ° C. In addition, the system can detect indoor humidity, according to the actual humidity and comparison settings to automatically adjust humidity. Man-machine dialogue interface is mainly used for temperature and humidity of the upper and lower limits setting and real-time display of temperature and humidity values.
