13671069882 Beijing central air conditioning refrigeration equipment recycling recycling Beijing, Beijing air conditioning recovery, central air conditioning central common common problems of Beijing Co., Ltd. The company specializes in classical recycling recycling Shanghai Kelly, Shuangliang, York, Sanyo, ambitious, Daikin McQuay, Trane and other brands 200,000 kcal -300 million kilocalories central air conditioning: chillers, lithium bromide chiller / screw machine, centrifuge, piston engine, air-cooled heat pump, water freezer unit, a ground source heat pump, suction temperature is too high - suction superheat is mainly due to the increase caused by the intake air temperature high note does not mean inspiratory pressure, because breathing is superheated steam. Under normal circumstances, should be half the compressor head cold, half hot. If the temperature is too high suction head all the heat. If the intake air temperature is higher than normal, the exhaust temperature will be a corresponding increase in Beijing central air conditioning recycling
