Classification and Characteristics

Based on application scenarios and design differences, household inverter heat pumps are mainly divided into two types: normal temperature type and low temperature type. Both types have their unique features in performance parameters, structural design, and applicable spaces.

Parameter/Type

Normal Temperature Heat Pump

Low Temperature Heat Pump

Operating temperature range

-10℃ to 43℃

-35℃ to 48℃

Applicable environment

It is mainly suitable for regular cooling and heating demands.

It is suitable for applications requiring operation under extreme temperatures.

Design features

Optimized compressor and heat exchanger design for regular temperature ranges

Additional heating and anti-freeze features to ensure stable performance at very low temperatures

Energy efficiency ratio (IPLV)

Higher efficiency, suitable for standard energy efficiency requirements.

Slightly lower than normal temperature type, but optimized for low temperatures.

The low-temperature household inverter heat pump is specifically designed for severely cold regions, boasting exceptional low-temperature startup and heating efficiency, as well as a broad operating frequency range. It can operate stably even in extreme low-temperature environments, ensuring a warm and cozy indoor space. The high-efficiency compressor and specially designed heat exchanger significantly enhance the system's heating capacity and energy efficiency under low-temperature conditions.


  • The heat pump is equipped with intelligent temperature control logic, which can intelligently adjust its operating mode based on external temperature and actual indoor demand, achieving precise temperature regulation.

  • The application of inverter technology not only optimizes energy efficiency but also keeps the heat pump operating at extremely low noise levels during low-temperature operation, providing a quiet and cozy living experience for the household.

  • The device integrates a comprehensive safety protection system, including low-temperature startup protection, antifreeze protection, and electrical safety protection, ensuring safe and reliable operation throughout the usage process.
