Ice rink - design of size of water storage tanks with small heat souree for ice resurfacing machine

摘要

The paper describes a method of design of storage tanks volume for an ice resurfacing machine in ice rink by using heat source with small thermal power (idea of downsizing). The main aim is to minimize investment costs for boiler room (the heat pump water-water). The achieved results show saving of investment costs about 35%. The request is the minimum water temperature at the value of 45°C before each filling process of resurfacing machine. Therefore it is very important to design the storage tanks volume where the water temperature will not be below the 45 °C before the each filling an ice resurfacing machine during the hockey match or training. The required volume of storage tanks was calculated at the value of about 2000 litres if there is used the heat source with thermal power 45 kW. The number of storage tanks is given by boiler room dimensions too. In this case 3 storage tanks were designed.
