Abstract: A heater unit includes a heater case and a high-voltage component disposed on a mount surface of the heater case. A protector is disposed in front of the heater unit. The protector includes a protection cover and a protection member disposed laterally of the high-voltage component. The protection member includes a side surface (support wall) disposed along a forward-rearward direction; that is, an assumed collision direction. The leading edge of the side surface protrudes further than the high-voltage component. The length of the side surface in the forward-rearward direction is longer than the length from a position on the heater case with which the side surface comes into contact in a collision to a front surface of the high-voltage component.

Abstract: A vehicular heater includes a heat medium circuit connected to a heater core that heats vent air via heat exchange with a heat medium. The heat medium circuit includes a first flow path connected to the heater core through a power unit, and a second flow path arranged in parallel with the first flow path and connected to the heater core through a heat source different from the power unit. A controller adjusts a first flow rate of the heat medium in the first flow path to be larger than a second flow rate of the heat medium in the second flow path when the power unit is operating.

Abstract: A refrigeration cycle device includes an outside evaporator, an inside evaporator, an evaporating pressure adjusting valve, a charging port, a pressure change buffer. The outside evaporator exchanges heat between a refrigerant flowing out of a heater and an outside air. The inside evaporator exchanges heat between the refrigerant flowing out of the outside evaporator and a heat-exchange target medium. The evaporating pressure adjusting valve is disposed at a position downstream of the inside evaporator and adjusts an evaporating pressure of the refrigerant in the inside evaporator. The charging port is disposed at a position downstream of the evaporating pressure adjusting valve. The pressure change buffer is disposed between the evaporating pressure adjusting valve and the charging port and defines a buffer space.
