本発明は冷媒流れの切換えによって冷房もしくは暖房を
行なう冷暖房装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating and cooling device that performs cooling or heating by switching the flow of refrigerant.

ヒータであるため消費電力が高く効率が悪いといった欠
点を有していた。In general, such air-conditioning equipment cannot exhibit sufficient capacity during heating operation when the outdoor temperature is low, and cannot correspond to the volume of the air-conditioned room commensurate with its cooling capacity. For this reason, recently, compressors used in air-conditioning machines have a higher capacity than those used in cooling-only machines, and circuits have been designed to reduce the capacity during cooling operation (refrigerant bypass system, etc.). Alternatively, a separate auxiliary electric heater is used to deal with the problem. However, the former method requires the use of a compressor with a larger capacity than necessary, resulting in poor cooling efficiency, while the latter method uses an electric heater, resulting in high power consumption and poor efficiency.

あり、以下その一実施例を添付図面に従い説明する。In order to solve the above-mentioned drawbacks, the present invention aims to increase the heating capacity by effectively utilizing the condensed refrigerant in the heating cycle without using a compressor with a particularly large capacity. An example will be explained with reference to the accompanying drawings.

続配置されている。- Inside the blade indoor unit 2, there is an indoor heat exchanger 9 which acts as an evaporator during cooling, a condenser during heating, and a condenser during heating. An auxiliary heat exchanger 1o is arranged in parallel on the windward side in the same ventilation area as the indoor heat exchanger 9, and a solenoid valve 11 is connected in series to circulate refrigerant to the auxiliary heat exchanger 1o only during heating operation. and a check valve 12, a distributor/cooling capillary tube 13 to the indoor heat exchanger 9, an indoor heat exchanger 9, and an auxiliary heat exchanger 10.
A blower 14 or the like for circulating indoor air is connected to both of the two.

れている。That is, in the cooling operation, the above-mentioned components are as shown by the solid line arrow in the figure.
- Indoor heat exchanger 9 - Four-way switching valve 4 - Achimulator 8
- The piping is connected to the compressor 3 so that it circulates, and during heating operation, the refrigerant flows through the compressor 3 - as shown by the broken line arrow in the figure.
Four-way switching valve 4 - indoor heat exchanger 9 - open solenoid valve 11 - auxiliary heat exchanger 1o - check valve 12 - heating capillary tube 6 - outdoor heat exchanger 5 - four-way switching valve 4 - The achievator 18 is connected to the compressor 3 by piping for circulation.

換器１ｏへは冷媒が循環しないため冷媒循環量の減少は
ない。Therefore, during cooling operation, the solenoid valve 11 is closed and the indoor heat exchanger 9 acts as an evaporator to cool the inside of the air-conditioned room. At this time, the refrigerant is not circulated to the auxiliary heat exchanger 1o by the solenoid valve 11 and the check valve 12, so there is no decrease in the amount of refrigerant circulation.

媒量調整手段を必要としない。In addition, during heating operation, the solenoid valve 11 is opened, and the refrigerant flows from the indoor heat exchanger 9 to the auxiliary heat exchanger 10 due to the resistance of the cooling capillary chest 13, and is condensed in the indoor heat exchanger 9. The auxiliary heat exchanger 10 obtains reheat after condensation, and also obtains sufficient supercooling of the refrigerant. Since the refrigerant circulates through the auxiliary heat exchanger 1o during heating compared to during cooling, surplus refrigerant is not generated and high/low pressure bypass and refrigerant amount adjustment means are not required.

おける余剰冷媒処理のための冷媒量調整手段、高低圧バ
イパス手段等を不用とすることができるものである。As is clear from the explanation below, according to the present invention, since the auxiliary heat exchanger through which the refrigerant circulates only during heating operation is installed in parallel with the indoor heat exchanger, the residual heat of the refrigerant after condensation contributes to heating. It is expected that the capacity of the system will be improved by increasing the degree of subcooling, and furthermore, it is possible to eliminate the need for refrigerant amount adjustment means, high-low pressure bypass means, etc. for processing surplus refrigerant during heating operation. It is something.
