A combined heat utilization method and a heat pump system utilizing nonaqueo us antifreeze solution and snow ice as a heat source wherein an automatic syste m for treating snow ice and utilizing cold heat is employed in a city, an airport or a railway station in a cold snowy region having a problem of conquering or utilizing snow without depending on manual work as much as possible, and snow treatment, high density storage and cold/hot heat utilization are unified into one system. The combined heat utilization metho d and the heat pump system are characterized in that nonaqueous antifreeze solution (2) is used as refrigerant in refrigeration cycle (ice snow heat source heat pump system (3)), the antifreeze solution is cooled to below the snow fall temperature for use as a medium for removing and carrying snow in winter season, the carried and stored snow ice is employed as a heat source and evaporation heat is absorbed, condensation heat of the antifreeze soluti on is employed for heating snow melting circulation fluid (9) in a region, othe r snow melting medium or heating circulation fluid, and snow ice cooled and stored in summer season is utilized as the cold heat source for cooling.</SD OAB>
