Small heat pump air conditioners - the environmental impact of their rapid growth.

In view of the rapid expansion of the heat pump market in Japan, a rough calculation has been made to determine the expected impact of the increased use of heat pump air conditioners on the environment. It was found that, through the use of heat pumps, the emission rate of substances into the environment can be reduced in comparison to the use of fuel oil. To make efficient use of this characteristic, measures to prevent the release of refrigerant from heat pumps are required.
