Abstract
Official abstract text for this publication.
A heat pump device includes an air conditioning control device configured to switch the heat pump device among a plurality of operation modes including an air-heating operation mode in which an indoor heat exchanger serves as a radiator and an outdoor heat exchanger serves as a heat absorber, and an air-cooling operation mode in which the indoor heat exchanger serves as a heat absorber and the outdoor heat exchanger serves as a radiator. The air conditioning control device switch a refrigerant pipe such that refrigerant is, in the air-cooling operation mode, supplied to part of the outdoor heat exchanger serving as a refrigerant inlet in the air-heating operation mode.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle air conditioner comprising: a heat pump including a compressor configured to compress refrigerant, a downstream indoor heat exchanger disposed inside a vehicle compartment, an upstream indoor heat exchanger disposed in a portion of the vehicle compartment upstream of the downstream indoor heat exchanger in a flow direction of air, and an outdoor heat exchanger disposed outside the vehicle compartment, and configured such that the compressor, the downstream indoor heat exchanger, the upstream indoor heat exchanger, and the outdoor heat exchanger are connected together through a refrigerant pipe; and an indoor air conditioner housing the downstream indoor heat exchanger and the upstream indoor heat exchanger, including an air blower configured to send air-conditioning air to the downstream indoor heat exchanger and the upstream indoor heat exchanger, and configured to generate conditioned air to supply the conditioned air into the vehicle compartment, wherein the refrigerant pipe includes a low-temperature refrigerant-dedicated pipe connected to the upstream indoor heat exchanger and configured to supply only low-temperature refrigerant to the upstream indoor heat exchanger, and a high-temperature refrigerant-dedicated pipe connected to the upstream indoor heat exchanger and configured to supply only high-temperature refrigerant to the upstream indoor heat exchanger, and the heat pump further includes an air conditioning controller configured to switch the heat pump among a plurality of operation modes including an air-heating operation mode in which the downstream indoor heat exchanger and the upstream indoor heat exchanger serve as radiators and the outdoor heat exchanger serves as a heat absorber, and an air-cooling operation mode in which the upstream indoor heat exchanger serves as a heat absorber, the downstream indoor heat exchanger serves as a radiator, and the outdoor heat exchanger serves as a radiator, and a flow path switcher configured to switch a refrigerant flow path such that high-temperature refrigerant from the downstream indoor heat exchanger flows through the high-temperature refrigerant-dedicated pipe in the air-heating operation mode and that low-temperature refrigerant from the outdoor heat exchanger flows through the low-temperature refrigerant-dedicated pipe in the air-cooling operation mode.
