Huangpu purchases可控硅rectifier cabinets and voltage regulator transformers for recycling. [Historical Knowledge of Refrigeration Units] Lithium bromide absorption refrigeration units were developed successfully in 1945. They can utilize low-temperature heat energy and have a relatively high thermal efficiency (approximately 0.7 for single-stage units), thus they have developed rapidly and are now widely used in air conditioning and other applications. There are various types of lithium bromide absorption refrigeration units, such as two-stage lithium bromide absorption units that effectively utilize high-pressure heating steam; two-stage absorption units that effectively utilize low-temperature heat energy; direct-fuel lithium bromide absorption units that can be heated directly by oil or gas combustion, etc. Lithium bromide absorption refrigeration units can also be combined with back-pressure steam turbines to form a joint unit, using the turbine's exhaust gas as the heating steam for the lithium bromide absorption refrigeration unit. This not only improves the utilization rate of steam but also meets several requirements, such as refrigeration and power generation. Based on this idea, a refrigeration unit has been designed that combines a lithium bromide absorption refrigeration unit with a centrifugal refrigeration unit using Freon. This unit is directly driven by a back-pressure steam turbine and utilizes its exhaust gas to heat the lithium bromide absorption refrigeration unit.

Excessive Refrigerant Charge in Air Conditioner】This issue typically occurs after maintenance, characterized by abnormally high suction and discharge pressures, balance pressure, and compressor operating current. The refrigerant should be vented under rated conditions based on the suction and discharge pressures, balance pressure, and operating current until normal. Air and non-condensable gases such as nitrogen are mixed in the refrigerant. This usually happens post-maintenance when evacuation is not performed. It can only be resolved by venting, re-evacuating, and refilling the refrigerant. False alarm caused by electrical fault.
