Turbomachine expander offers efficient, safe strategy for heating, cooling

A new device to help homeowners cut electricity bills also could provide more efficient and safer cooling options for companies and vehicles.

Researchers developed their device to decrease energy consumption of the vapor-compression heat pump cycle, which is commonly used in homes, businesses and vehicles for cooling and heating.

The team created a novel turbomachine expander that helps harvest previously wasted energy used in the process of moving the air from high to low pressure.

The device can be used as a control agent within an existing heat pump.
