The new Hydrus AC from Heatstar is designed to meet the diverse environmental control needs of moving-floor pool rooms – while complying with the recently implemented European Union Directive for ‘Energy Related Products’, and even exceeding more-stringent regulations proposed for the future.

The Hydrus is claimed to be able to handle the strenuous demands of a high-temperature and moisture-laden swimming pool room environment, as well as the entirely different environmental requirements when the room is being used ‘dry’ for events such as functions and parties.

When the moving floor is open and the pool is in full use, the room can be heated (or cooled) to a temperature of 30–32°C. The Hydrus AC provides room dehumidification, and also recycles the heat energy captured by the heat pump back to air or the pool water.  Active energy recycling efficiencies of up to 380% are possible through this process, according to Heatstar. High-rate fresh-air dilution and extremely energy-efficient pool water heating are claimed additional benefits.

Meanwhile when the pool is not in use and the floor is closed, the room air in this mode is usually heated or cooled to around 21–23ËšC.

The Hydrus AC can provide cooling to the room either by introducing outside fresh air or, if the fresh air is too warm, by using a refrigeration mechanical air cooling system. A fresh air temperature sensor automatically determines the optimum method, and priority is given to fresh air ‘free’ cooling when possible. The refrigeration cooling system features an integral fresh air condenser, obviating the need for any noisy or unsightly condenser units located outside the building.

The Hydrus AC provides fresh air dilution to maintain air freshness and to prevent any build-up of chemical odours. A slightly negative air pressure helps prevent the room atmosphere from migrating into adjoining areas or compromising vapour barriers.
