Alpha Heat Pump
จากประเทศ China
The YASBP series is external-air to water heat pumps recovers heat contained in the ambient air and transfers it to the water via a refrigeration compression cycle. Only a fraction of the total thermal energy output of the heat pump is consumed as electrical energy. Heat pumps therefore provide an energy efficient alternative to conventional heating plants. The running cost can be as little as 25% of an electric water heaters.
