Designing a control system to adjust the plant operation in accordance with both changing climate and facilities utilisation
At both the swimming pool and the ice rink, cooling and heating energy can be significantly reduced if the fresh supply air flow rates to the space are kept to the minimum. Variable speed control has been provided to the pool air system to ensure only minimum fresh air supply air flow to meet the heating and condensation control requirement. Recirculation control has been provided at the ice rink to limit the fresh air supply to meet the air quality control requirements.
Preventing freezing of system components due to low temperatures
The use of a single low temperature system for all cooling and heat pumping needs has the advantage of low capital and maintenance cost. This system however, requires anti freeze protection at cooling and heat pump coils, including all control and safety valves. The use of the cascade circulation system has also substantially reduced the risk of freezing.
Balancing the heating demands with the heat sources
The primary heat sources are the heat extracted from of the ice rink space cooling and ice bed cooling, plus the associated compressor heat. If heat from these primary sources is not sufficient to meet the demand, heat will be extracted from the exhaust air from the pool hall. A fine balance will ensure the chiller will operate at its optimum efficiency.
