A climate control system of a motor vehicle having a refrigeration circuit and a coolant circuit. The refrigeration circuit includes a compressor, a refrigerant-coolant heat exchanger operable as a condenser/gas cooler for heat exchange between the refrigerant and the coolant of the coolant circuit, and at least one first refrigerant-air heat exchanger for conditioning intake air for the passenger compartment having a first expansion element upstream in a flow direction of the refrigerant. The coolant circuit includes a conveyor device, a first coolant-air heat exchanger heating the intake air for the passenger compartment, and the refrigerant-coolant heat exchanger. A refrigerant-air heat exchanger for exchanging heat between the refrigerant and ambient air is provided. The refrigerant-air heat exchanger is arranged downstream of the first refrigerant-coolant heat exchanger in the flow direction of the refrigerant. An expansion element is upstream of the refrigerant-air heat exchanger in the flow direction of the refrigerant.

In the application, since the flow of air outside the vehicle compartment flowing through the upstream heat exchange part and the flow of air outside the vehicle compartment flowing through the downstream heat exchange part are opposite flows, a second heat exchanger through which the air outside the vehicle compartment flowing from the first fan through the downstream heat exchange part flows, a first heat exchanger is an orthogonal heat exchanger, the second heat exchanger that is a component of a refrigeration cycle execution system, the air in the vehicle compartment, which flows in from the inside air inlet by the rotation of the second fan and is discharged from the outlet outside the vehicle through the first heat exchanger, and the air outside the vehicle compartment, are exchanged with the first heat exchanger, it can be miniaturized along with the improvement of electricity cost.

A passive vehicle cabin insulation method with constant temperature and ultra-low energy consumption. It accomplishes this through the implementation of several special features in different parts of the vehicle. These features include a layer of efficient heat insulation material, an airtight casing, windows insulated with multiple layers of vacuum, energy-saving, laminated glass, an anti-UV heat insulation coating, an efficient fresh air circulation and heat recovery system, a broken bridge structural design, and an anti-fog and hazy air purification system. The method insulates the vehicle sufficiently to deal with the heat of summer and the cold of winter. It also makes full use of passive renewable energy, and maintains a healthy and comfortable driving environment within the vehicle. Specifically, it maintains a constant temperature, constant humidity, constant oxygen levels, constant levels of air purity, and low noise, all while consuming a minimal amount of energy.

A vehicle air-conditioning apparatus includes: an indoor heat exchanger that evaporates a refrigerant; a cooperative device group that forms, with the indoor heat exchanger, a refrigeration cycle; a waste heat recovery part that recovers waste heat from a waste heat source and a heat-release part that releases, to an indoor heat exchanger, heat transmitted to the heat-release part, and that is switchable between (a) a heat-releasing state in which the waste heat recovered by the waste heat recovery part is transmitted to the heat-release part, and (b) a heat-release-stopped state in which the heat recovered by the waste heat recovery part is less transmittable than when in the heat-releasing state; and a controller to switch between (i) a heat-release-stopped state when the refrigerant is being exchanged between the indoor heat exchanger and the cooperative device group, and (ii) a heat-releasing state when the exchange of the refrigerant is stopped.
