て、その構成を第１図によつて説明する。 Conventional multi-room air-conditioning systems are capable of either switching operation of one indoor unit or simultaneous operation of multiple rooms; however, for example, in the middle of the season, rooms on the south side require cooling, while rooms on the north side require cooling. If heating is required, conventional multi-room heating and cooling systems cannot meet such demands. The present invention is a completely new air-conditioning and heating system that can meet these demands and effectively utilize the heat absorbed from the room on the cooling side as a heat source for the room on the heating side. This will be explained using figures.

る作用を行うものである。 Figures 1, 2, 3, and 4 above show normal cooling and heating operations, but Figure 5 shows the refrigerant circuit when indoor unit Aa performs heating and indoor unit Ab performs cooling. At this time, the indoor unit
The first on-off valves 10a, 10b, the second on-off valve 11a, and the fourth on-off valve 12a are activated in response to the difference between the heating and cooling commands from the operation switch of Aa and the heating and cooling command from the operation switch of indoor unit Ab. Open, third
When the on-off valve 9, the second on-off valve 11b, and the third on-off valve 12b are closed, and the four-way valve 2 is switched to the heating side, the high-pressure refrigerant gas compressed by the compressor 1 is distributed in all directions as shown by the solid arrow. The refrigerant enters the indoor heat exchanger 4a in the indoor unit Aa through the valve 2 and the second on-off valve 11a, where it condenses and liquefies and heats the room.
The liquefied refrigerant flows through the check valve 8a and the first on-off valve 10.
a, 10b, enters the indoor unit Ab, is depressurized by the cooling diaphragm 6b, enters the indoor heat exchanger 4b, where the refrigerant evaporates and cools the room, and the evaporated refrigerant gas is passed through the fourth opening/closing circuit. The air is sucked into the compressor 1 again through the valve 12a. That is, here, the indoor unit Aa performs a heating operation, and the indoor unit Ab performs a cooling operation, and the heat absorbed by the indoor unit Ab is effectively used as a heating heat source for the indoor unit Aa. In contrast, FIG. 6 shows a case where indoor unit Ab performs heating and indoor unit Aa cools the room. In this case, the first on-off valves 10a, 10b and the fourth on-off valve 12b are open, and the When the on-off valve 9 of No. 3, the second on-off valve 11a, and the fourth on-off valve 12a are closed, the refrigerant discharged from the compressor 1 flows as shown by the solid line arrow and performs the intended action. .
