Abstract: A refrigeration cycle device includes an interior condenser that exchanges heat between a high-pressure refrigerant and ventilation air to heat the ventilation air, an exterior heat exchanger that exchanges heat between outside air and the refrigerant downstream of the interior condenser, an interior evaporator that exchanges heat between a low-pressure refrigerant downstream of the exterior heat exchanger and the ventilation air before passing through the interior condenser, and an internal heat exchanger that exchanges heat between the refrigerant flowing out of the exterior heat exchanger and the refrigerant flowing out of the interior evaporator. The refrigeration cycle device further includes a gas-liquid separator that separates the refrigerant at a downstream side of the interior condenser into gas and liquid phase refrigerants. In a dehumidification heating mode of evaporating the refrigerant at the exterior heat exchanger, the liquid-phase refrigerant separated by the gas-liquid separator flows into the exterior heat exchanger.

Abstract: A cold storage heat exchanger includes multiple refrigerant tubes, a cold storage container that is bonded to the refrigerant tube and defines a compartment receiving a cold storage material, and an inner fin arranged inside of the cold storage container. The cold storage container has a portion that stops and fixes the inner fin, and the cold storage container has a space where air is sealed. The space of the cold storage container is located at an upper side of the member that stops and fixes the inner fin. Accordingly, a stress applied to the cold storage container in the expansion of the cold storage material can be reduced.

Abstract: A regenerative heat exchanger includes a refrigerant pipe, a regenerator, and an air passage fin. The air passage fin is disposed in an air passage defined outside of the refrigerant pipe and the regenerator, and is thermally connected with the regenerator directly or through the refrigerant pipe. At least one of the regenerator and the air passage fin is configured such that a thermal resistance between a part of a regenerative material located on an upstream side and air flowing through the air passage becomes larger than a thermal resistance between a part of the regenerative material located on a downstream side and air flowing through the air passage.
