Abstract
Description
Technical Field
[0001] The utility model relates to an air-conditioning refrigeration system, in particular to an oil-electric dual-drive air-conditioning refrigeration system for heavy trucks. Background Art
[0002] With the development of society and the advancement of technology, the vehicle cab is no longer simply a driving space, but has become more prominent in the needs of mobile office and rest, and has put forward more requirements for vehicle air conditioning. Traditional air conditioning that relies solely on vehicle engine drive can no longer meet the requirements.
[0003] Traditional vehicle air conditioners currently on the market are mostly engine-driven. If the air conditioning is required while parked, the vehicle must remain connected. Heavy trucks used for mobile office or logistics operations often spend far more time parked than in motion, making traditional vehicle air conditioning ill-suited for these applications. Furthermore, with increasingly stringent environmental regulations, continued use of the air conditioner while parked increases carbon emissions. To address this, a hybrid electric air conditioning and refrigeration system utilizes two drive systems to meet the demands of driving and parking conditions. Utility Model Content
[0004] The utility model discloses an oil-electric dual-drive air conditioning refrigeration system for heavy trucks. The refrigeration system uses an engine-driven pulley compressor for cooling when the vehicle is driving, and uses a battery or three-phase electric drive electric compressor for cooling when the vehicle is parked. This system can meet the requirements of different working conditions. At the same time, the two sets of evaporators connected in parallel in the cab can significantly improve the cooling effect.
[0005] The utility model is realized by the following technical solutions:
[0006] A dual-drive oil-electric air-conditioning refrigeration system for a heavy truck comprises a pulley compressor, an electric compressor, an oil-gas separator, a condenser, a liquid storage tank, an expansion valve, an engine and an evaporator, wherein the pulley compressor and the electric compressor are respectively connected to one open end of a condenser tee via a one-way valve, the third open end of the condenser tee is connected to the condenser, the condenser is connected to the liquid storage tank and the first evaporator tee in sequence, the second and third open ends of the first evaporator tee are respectively connected to the expansion valve, the evaporator and the second evaporator tee in sequence, the third open end of the second evaporator tee is connected to the compressor tee, the other two open ends of the compressor tee are respectively connected to the pulley compressor and the oil-gas separator, the oil-gas separator is connected to the electric compressor, and the pulley compressor is connected to the heavy truck engine.
[0007] A blower is provided beside the evaporator.
[0008] A fan is provided beside the condenser.
[0009] The evaporators are two groups of parallel evaporators.
[0010] The electric compressor is provided with a power plug, which can be connected to a battery or three-phase electricity.
[0011] The refrigeration system of this utility model uses the engine to drive the pulley compressor for cooling when driving, and uses the battery or three-phase electric drive electric compressor for cooling when parked, which can meet the use requirements of different working conditions. At the same time, the two sets of evaporators connected in parallel in the cab can significantly improve the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS
