Abstract

PURPOSE: To provide a heat pump, in which, upon switching a four-way valve by way of switching signal, the four-way valve is actuated after the pressure difference between a high pressure side and a low pressure side is made small, so that switching of the four-way valve can be effected by a motor having a low torque.
