变频空调市场启动 膨胀阀销量剧增（Inverter air conditioning market started expansion valve sales surge） Inverter air conditioning market started expansion valve sales surge According to the air conditioning and refrigeration market procurement data show that with the inverter air conditioner market in full swing, the upper parts of supply chain with the whole plant needs to make the corresponding adjustment, and the electronic expansion valve is one of the most important parts of head of inverter air conditioner, its sales surge, according to air conditioning and refrigeration market experts predict that in 2010, China inverter air conditioner sales will achieve more than 100% growth, this will give the expansion valve production and sales bring new surprises. As the main producers of electronic expansion valve, Zhejiang spent three Limited by Share Ltd responsible person told the reporter: three Citigroup refrigeration letters under the electronic expansion valve business development soon, 2010 1~6 months, the production and sales of electronic expansion valve about 1 million 700 thousand units, almost more than 2009 full year sales in 2010, annual sales will likely exceed 3 million units. Electronic expansion valve is a throttling valve in the refrigeration system. It plays a role in controlling the flow of refrigerant. It is mainly used in the control of variable frequency air conditioning system in the production area of household air conditioners. And in the constant speed air-conditioning, refrigeration system to play refrigerant flow control, regulating the role of capillary and thermal expansion valve. Electronic expansion valve controller drive is collected by the sensor parameters were calculated, the issue of regulation of instructions to the driver board, the driver board output signal to the electronic expansion valve, electronic expansion valve driver moves this process in a few seconds. From the point of view of the matching requirements of the air conditioner, the el
