This standard applies to indoor pool dehumidifiers using electrically driven@ mechanical vapor-compression refrigeration systems consisting of one or more factorymade assemblies that dehumidify and circulate air and may include pool water heating@ air reheating@ cooling@ filtering@ and heat recovery. Systems other than the above are excluded. PURPOSE The purpose of this standard is to prescribe test methods for determining the moisture removal capacity and efficiency@ the pool heating capacity@ and sensible and total cooling capacity for indoor pool dehumidifiers.
