Patients at a specialist orthopaedic hospital are reaping the benefits of a purpose-built hydrotherapy pool that features an HRD 25 – a purposedesigned swimming pool dehumidification, ventilation and heat recovery air handling package from manufacturer Calorex of Essex.
HRD systems offers 300% heat recovery to pool water and/or pool hall air compared to 50-60% from recuperator type air handling units (AHU) and reduce energy usage by up to 60% while associated CO2 emissions are cut by up to 55% when compared to a full fresh air ventilation system with cross plate heat exchanger. On a typical leisure centre with 25m and learner pools for instance, an HRD system can reduce C02 emissions by 250 tonnes per year.
Hydrotherapy plays a vital role in the rehabilitation of patients and the new pool offers a valuable resource to the NHS Trust run centre of excellence.
Maintaining high water temperatures are vital to the comfort of patients using the pool and HRD systems provide an environmentally-friendly solution by maintaining required water temperatures while minimising the impact on the pool hall and the building structure itself.
Smaller than a conventional AHU, the Calorex HRD recovers the latent energy available in the moisture laden air of a pool hall. It can then return the energy to heat the pool water or use it to assist with pool hall air heating. There is usually sufficient recovered energy to provide all the operational water heating requirements with some left for air heating.
What is more, the HRD systems are supplied as fully packaged units including all controls, which saves installation time and the need for an additional control panel is eliminated.
