PROBLEM TO BE SOLVED: To obtain a heat pump type cooling and heating device capable of coping with any demand having a high thermal load. SOLUTION: This heat pump type cooling and heating device is so constituted that the heat medium of a heat transfer circuit can be heated not only by a thermal gas engine 1 but also by a heating means 55 indirectly through a heat exchanger 90 for heating. Accordingly, the cooling and heating device can cope with any demand having a high thermal load (quick heating and the like) which can not be coped with by only the thermal gas engine 1 and, further, the heat exchanger 90 for heating is not heated directly by a heating means but is heated indirectly through a heating medium and, therefore, the heat exchanger can not only be heated stably but also can increase the possibility of utilizing it for another use since the heat exchanger 90 for heating is equipped with utilizing heat exchangers 51, 53. |
