Couple Heat Pump with traditional heating technology to complement the required outputs. How a heat pump works Air to water and Water to water Heat Pumps takes energy from the air/water and raise it to a higher temperature, using a process which is similar to a reverse refrigeration process. A Heat Pump absorbs the heat energy from (air or water) to another location (a hot water tank or pool). Its principle uses the refrigeration process to transfers low temperature energy (device called evaporator heat exchanger) to a refrigeration loop, the compressor compresses the gases (heat) to a high temperature and transfers this heat to the hot water and heating distribution system (device called condenser heat exchanger). The refrigerant circulates and an expansion valve lowers the pressure and the refrigerant becomes cold again. This process repeats continuously such that 1 unit of input energy plus absorbed 3 units of energy can product 4 units of heat energy. 3

Air to Water Heat Pump Air Source Heat Pumps absorb heats from the outside air and raise it to a higher temperature, using a process which is similar to a reverse refrigeration process. Air Source Heat Pumps can be used in many more applications including large commercial projects, swimming pools, sports utilities, hotels, club house, SPA, health care facilities, schools, apartments and food industry. Air Source Heat Pump run on electricity, it helps prevent global warming because no wasted heat discharged to outdoor as compare to gas or oil boilers. Air Source Heat Pumps can be add-on as supplementary source of heat to pre-heat water before enter to existing gas or oil boilers. They can also be used in commercial building to recover heat from exhaust air, or as a dehumidifier to remove moisture in indoor swimming pool, and transfer the recovered heat to incoming fresh air or hot water. Exhaust (ventilation) air is a common heat source for heat pumps in residential and commercial buildings. The Heat Pump recovers heat from the ventilation air, and provides water and/or space heating. For large buildings exhaust air heat pumps are often used in combination with air-to-air heat recovery. 6

Water to Water Heat Pump Water to Water Heat Pumps (Water Source Heat Pump) Cooling and heating account for more than 60% of the energy used in building, make it the largest energy expense for most owners. A Water to Water Heat Pump provides both cooling and heating and offer the most benefit of delivering more useful energy than consume. The Water to Water Heat Pump contains a source-side water-to-refrigerant heat exchanger (evaporator), and a loadside refrigerant-to-water (condenser) heat exchanger. The source-side is typically connected to the central airconditioning system (chilled water) and the load-side connected to the hot water system. During the refrigerant cycle, heat is transferred from the source-side heat exchanger to the load-side heat exchanger. The source-side provides chilled water to central air-conditioning plant for cooling and simultaneously the load-side provides hot water to the domestic hot water system or pool water heating. Water to Water Heat Pump make use of the building cooling load as a heat source for hot water heating, it reclaim the heat instead of reject to outdoor, thus achieves added efficiency, energy saving and kind to the environment. Many industries need space cooling in their process, and often have a significant hot water demand in the temperature range from 40~65 degree C for washing, sanitation and cleaning purpose. Water to Water Heat Pump can be a part of an integrated system that provides both cooling and heating. Water to Water Heat Pump meets space cooling and hot water heating in building, typical applications include large hotels, sports utilities, club house, SPA, health care facilities, and food industry. 8

Swimming Pool Heat Pump FEATURES Refrigeration design Dual refrigerant circuit design allows staging to minimize energy consumption and optimize energy recovery. The system combines of air coiling coils, reheat coils, water (pool) condensers or remote condensers. Circuit A recovers the energy to the air or water, it balance the heat lost due to evaporation on water surface. Circuit B allows the system to recover energy, or absorb heat from ambient and deliver it to the space in the winter but reject the heat for cooling in the summer. The dual circuit design provides simultaneous recovery of heat to water and air, its independent refrigerant circuit provide versatile capability to control indoor air quality accurately. DX Cooling / Reheat Coils All cooling and reheat air coils have a specifically designed epoxy coat or E-coat to protect Aluminum and copper surfaces. As unprotected coils corrodes, heat transfer capacity diminished and cooling capacity reduced, extend maintenance time is required to repair the system. Coils are protected from corrosion without affecting heat transfer, is ideal for application in environments with a high chloramines compounds, hazardous commercial areas and industrial sites. Condensers (refrigerant to water heat exchangers) All condensers are chemically cleanable. Condensers are coaxial tube-in-tube or shell and tube type for maximum heat transfer efficiency and performance. Inner water tubes are either Cupro-nickel or Titanium (selectable option) with large internal diameters for reduced water-side pressure drops. Double skin inner tube are available as option. Outer tubes or shell are steel, painted for corrosion protection. Filters All units come with standard 25mm thick efficiency washable filters. Optional filters are available. Filters are removable from the sides of the frames through filter access panels. Cooling or Heating Water Coils (Optional) When chilled water or hot water is available, water coils can be factory-installed upstream of the supply fan. The coil has a factoryinstalled and wired three-way flow control valve and is controlled by the unit s control system. Casing and Framework Heavy-duty structural support with Aluminum alloy framework. All metal frame and panels use a special corrosion resisting galvanize steel with a powder coat finish on exterior, a tough coating that resists rusting. The frameworks are designed for ease of disassembly and re-assembly. All panels are insulated with 50mm thick high density PU insulation for thermal and acoustic performance. All components are located for ease of inspection and service. Major components are out of the unit s air stream to allow maintenance while the unit is in operation. Service access is through the removal of access panels located on the unit. All refrigerant components are accessible from the front of the unit for service and maintenance. The unit can be installed either indoors or outdoors. Units intended for outdoor installation are factory equipped with additional cover, heavy duty weather sealing. 18

Swimming Pool Heat Pump Refrigerant components are accessible from the front of the unit for service Ventilation Fans Ventilation fans contain either one or two forward curved medium-pressure class fan assemblies depending on the model size. The fans are double inlet double width, welded assemblies statically and dynamically balanced. The fan is isolated from the main module by the use of springs which provide excellent vibration isolation and quiet operation. The modules are bolted together with bolts and locking nuts. Each fan is powered by its own motor and drive assembly. Motors are mounted on individual motor platforms for stable operation and belt tension adjustment. Remote Air-Cooled Condenser (Optional) It can be equipped with a properly sized high efficiency air-cooled condenser rejects excess heat to the outdoors when in cooling operation. There is also optional remote water condenser available, the sensible and latent heat recovered in the air-conditioning is rejected to the water condenser if pool water temperature requirement is satisfied. Indoor Pool Dehumidification A well-designed and installed dehumidification system controls both temperature and humidity levels. A typical residential or commercial indoor pool conditions is: The water temperature is set at 24 C to 30 C. The air temperature is set at two degrees above the pool water temperature. The relative humidity is maintained between 50% and 60%. Humidity control, ventilation, air distribution, pool water chemistry and evaporation rates are major considerations in satisfying comfort requirements. High humidity can increase levels of bacteria, viruses, fungi and other factors that reduce air quality. It is also destructive to building components. 19

Swimming Pool Heat Pump Modes of Operations SustainE Natatoriums indoor swimming pool dehumidifier systems are flexible in their design operations. This concept allows each system to be customized for specific dehumidification applications. Each mode of operation is described below. Dehumidification and Reheat Auxiliary chilled / hot water coil control This is the basic option which removes moisture from the air at the evaporator coil and reheats it before returning to the space as dehumidified air. Dehumidification, Reheat & Water heating (pool) Instead of rejecting the heat to the reheat coil, the three-way valve on one refrigerant circuit divert hot gas to the water condensing coil to reject heat to the pool water. Either circuit can become the primary heat sink allowing the circuit s latent and sensible heat to be directed to a water source or returned to the air. Air-conditioning & Remote condenser This is very similar to the dehumidification & reheat, instead of sending recovered energy to a reheat coil, the energy is rejected to an outdoor condenser. Dehumidification, Air-conditioning & Remote condenser The unit controller will send a 0-10V (or other variable control voltage) to a modulating control valve. The function of the coils shall be clearly specified by the client. The unit controller will modulate the water coil valves as the specified by client. The control valve is supplied and installed by others. Ventilation Every indoor swimming pool requires the introduction of outdoor ventilation air during occupied times. The unit offers (optional) variable speed drive fans to integrate ventilation air into the dehumidification package. The dehumidifier blower will act as the ventilation fan and supply air blower. The unit controller can reduce fan speed to save energy when the occupancy level of the swimming pool is low. The ventilation system simplifies air balancing while maintaining the correct proportions of return air, supply air, exhaust air and outdoor air. This is the combination of all heat sink options. It is used when only a partial water heat sink is available but full capacity dehumidification is required continuously, regardless of season. Air Source Heat Pump in cold weather (selectable option) Even though recovered energy is sent to the space during the dehumidification process, the heat loss of the space can be greater in cold weather. Auxiliary heating may be required. One of the refrigerant circuits can be operated as an Air Source Heat Pump to provide efficiency heat energy to complete indoor climate control in one package. More than 60% saving in operation cost during cold season can be obtained as compared to auxiliary electrical heating elements. Minimum Maintenance Space. Reliable operation. Energy efficiency.

Swimming Pool Heat Pump Humidity and moisture of indoor pools Effective control of indoor pool humidity help prevent bacteria, viruses, fungi and protect building components. The amount of water evaporated from an indoor swimming pool depends on: 1. The surface area of the swimming pool. 2. The water temperature of the swimming pool. 3. The indoor air temperature and relative humidity. 4. The air velocity over water surface. Calculation of dehumidification requirement based on water evaporation rate from ASHRAE APPLICATION HAND- BOOK. (The following sections are relevant extraction from ASHRAE handbook - Nataoriums) Internal latent loads are generally from people and evaporation. Evaporation loads in pools are significant relative to other load elements and may vary widely depending on pool features, areas of water and wet deck, water temperature, and activity level in the pool. The rate of evaporation can be estimated from empirical Equation (1). This equation is valid for pools at normal activity levels, allowing for splashing and a limited area of wetted deck. Where Wp = (A/Y)(Pw Pa)(0.089 + 0.0782V) (1) Wp = evaporation of water, kg/s A = area of swimming pool surface, m² Y = latent heat required to change water to water at surface water temperature, kj/kg Pw = saturation vapor pressure taken at surface water temperature, kpa Pa = saturation pressure at room air dew point, kpa V = air velocity over water surface, m/s (The units for constant 0.089 are W/(m².Pa); the units for the constant 0.0782 are (W.s)/(m.Pa)) Equation (1) may be modified by multiplying it by an activity factor (Fa) to alter the estimate of evaporation rate based on the level of activity supported. For Y value of about 2400 kj/kg and V values ranging from 0.05 to 0.15 m/s. Equation (1) can be reduced to Wp = 0.00004 A(Pw Pa)(Fa) (2) Type of Pool Typical Activity Factor (Fa) Baseline (pool unoccupied) 0.5 Residential pool 0.5 Condominium 0.65 Therapy 0.65 Hotel 0.8 Public, schools 1.0 Whirlpools, spas 1.0 Wavepools, water slides 1.5 (min.) 23
