Air-conditioning and heating out snow heat collection manner and the device null by the heat storage utilization

摘要

PURPOSE:To save energy by guiding cold water from a terminal end of a pipe to an evaporator of the second heat pump, absorbing heat heat pump to make hot water and repeating a water pumping-up operation and a water returning operation every year. CONSTITUTION:Cold underground water passed through an evaporator 10a of a heat pump 8 is passed in a pipe 17 buried in a pavement 16 so as to store heat within the pavement 16, snow fell on the pavement is melted with radiation of this heat and then a freezing at the pavement surface is prevented. During a heating operation, water is also passed during no snow fall to radiate heat from the pavement surface, then the cooled cold underground water is guided again to an evaporator 10b of the second heat pump 9, the underground water cooled to a more cold state and controlled is passed through the second water feeding pipe 6 with its lower end being buried in water in a cold well, returned back to the underground aquifer 24 from a cold water well 2 and stored to keep cold heat in water of which heat is absorbed and its temperature is increased during a refrigeration cycle of the second heat pump 9.
