An absorption type cooling and heating system including a generator, an outdoor heat exchanger, pressure reducing devices, two indoor heat exchangers, an absorber, a solution pump, change-over valves, on-off valves and check valves, wherein in a cooling mode the outdoor heat exchanger functions as a condenser and the two indoor heat exchangers function as evaporators and in a heating mode one of the two outdoor heat exchangers functions as a condenser, the other outdoor heat exchanger functions as an absorber and the outdoor heat exchanger and the absorber function as evaporators, so that the heat of a refrigerant in a gaseous state of high temperature and the heat of absorption generated at the absorber can both be utilized as heating heat sources. In a defrosting mode, the outdoor heat exchanger and the absorber function as condensers and one of the two indoor heat exchangers functions as an absorber, so that space heating can be carried out even during the defrosting mode.
