When the system operates under extreme cold conditions, the compressor supplies mid-temperature vapor to increase the total amount of compressed refrigerant so that the heating performance is enhanced.

High efficiency compressor motor and optimized exhaust channel result in a large discharge capacity

Horizontal discharge fan allows optimal airflow between the air-side and refrigerant-side.

The unit structure with horizontal fan and vertical heat exchanger guarantee more uniform and efficient heat exchanging velocity across the entire heat exchanger surface. When the temperature gets low, the system shows higher heat exchanging efficiency and provides stronger heating output.
