Electric and hybrid cars use high voltage A/C compressor to compress the refrigerant.
Guchen HP350 compressor is a heat pump DC350V electric scroll compressor
, not dependent on the running of the combustion engine when running A/C. Its cooling capacity could reach the maximum value of 7.6KW.
Guchen HP350 electrically driven compressor is capable of providing cooling capability during engine stop. This makes for more thermal comfort when passengers ride on electric vehicles.
34cc/350V Heat Pump Electric Compressor
The 34cc heat pump compressor unit
can produce between 1-7.6kw and is available in 350 volt.
The heat pump scroll compressor
is dedicated manufactured with a over-voltage and under-voltage protection, which is a low voltage, high voltage & quick voltage fluctuation cut out function.
Low voltage cut out (won't operate below) @350V = 200V
High voltage cut (cannot exceed) @350V = 400V
Some Need-to-Know Facts on Guchen High Volt Electric Air Conditioner Compressor
◆ The electric vehicle A/C compressors used in hybrid vehicles are driven by a high-voltage electric motor. It requires RL68H Polyol Ester (POE) oil which is a specific type of AC refrigerant oil that is non-conductive.
◆ The electric compressor inverter is integrated with the compressor. The inverter-integrated construction makes the AC compressor compact, significantly improving electric compressor installability in hybrid and electric vehicles (cars, buses, trucks, vans etc.)
◆ The HP350 operates between 200-400 VDC and has 34cc/rev of displacement.
◆ 1) Do not attempt to disassemble the electric ac compressor yourself, otherwise the warranty will be voided; 2) No warranty will be given on any repair. If there’s something wrong with your compressor, please contact with our technicians at first: email@example.com
◆ Guchen offers both high voltage AC compressor
and low voltage electric compressor units
for EV (electric vehicles) and HEV (hybrid-electric vehicles) applications

Dedicated Design of 350V Heat Pump Scroll Compressor
◆ the most advanced assembly
Guchen EAC optimizes the structure of static scroll plate of electric scroll compressor
, based on the method of air enthalpy difference. Key components in the heat pump electric compressor include elements as a variable speed scroll compressor and a reversible air-to-air heat pump. The novel design of HP series heat pump electric compressor
improves its heating and cooling capability.
They are available to handle input voltages of 200 to 400VDC to provide operator comfort and to meet the comfort requirements of today’s electric vehicles in winter and summer.
◆ Increased Heating Performance when Operated in a Cold Climate, Compared with ordinary electric air conditioning compressors.
A heat pump compressor with vapor injection technology
is dedicated designed for electric vehicle air conditioning system, to improve its heating performance in winter days. Though barriers remain, there are still many top picks that makes heat pump scroll compressor the top choice for EV manufacturers.
It was tested that under a low (-10℃) ambient temperature, the heat pump electric compressor
will achieve an average improvement of 30% in heating capacity, when compared with other electric compressors.
PS: The heating performance of heat pump system when operated in extremely cold regions is still under test.
◆ the most advanced process control techniques
The most advanced soft starting technology is adopted to provide adjustable voltage to the motor, resulting in a smoother starting performance of the heat pump electric compressor. The innovative electric designs of the compressor allow the electric vehicle A/C operating more smoothly.
