PURPOSE:To provide the title system so designed that the turf in the greens in a golf course is cooled or warmed through an air-cooling or water-cooling heat pump-type chiller unit, thus effecting energy saving for the cooling-and- warming of the turf by cool or warm water. CONSTITUTION:A many of pipings 3 are embedded just under a turf 2 so as to be located on a thermal insulating material 4. Using an air-cooling or water- cooling heat pump-type chiller unit is connected, via a four-way changeover valve 11, through a heating medium-circulating pipe 6, to an air heat exchanger 5, a water heat exchanger 7 and a compressor 10, said turf is warmed via a heating medium 8 in winter season, while cooled in summer season. |
