product features
- Function: heating and cooling
- The ultra-low temperature heat pump unit has a very wide application range and can operate stably at an outdoor temperature of -25℃ to 43℃ degrees Celsius.
- The ultra-low temperature heat pump adopts advanced energy-adjustable control technology to control the number of compressors in the system modules and unit modules, so as to output energy according to actual needs.
- Intelligent defrosting technology to reduce heating attenuation: The unit can accurately judge the timing of defrosting according to the main parameters of heating operation and load changes, so as to achieve defrosting with frost and normal heating without frost. Forced manual defrost.
- Multiple protection functions to ensure the safe operation of the system.
Ultra-low temperature heat pump applications
Hotels, shopping malls, office buildings, exhibition halls, airports, gymnasiums, and other public places, and can meet the different requirements for the use of air-conditioning systems in industries such as electronics, pharmaceuticals, biology, textiles, chemicals, metallurgy, electric power, and machinery.
