1 AQUATECH Heat Pump Temperature Control System for Swimming Pools

With more and more swimmin g pools built at substantial costs, efficient methods of pool heating and cooling have become a necessity so as to provide maximum comfort while swimming.

2 With more and more swimmin g pools built at substantial costs, efficient methods of pool heating and cooling have become a necessity so as to provide maximum comfort while swimming. Today, the most inexpensiv e solutio n of maintainin g the pool water temperature at comfortable levels with greater degree of control on both new and existing installations are the Aquatech Heat Pumps. Because the AQUATECH Heat Pumps efficientl y capture s heat from ambient air and transfer s it to swimming pool water, it has been tested and proven to be five times more efficient than the traditional heaters and other conventiona l methods. Additionall y, it is economical because it consumes minimal electricity only to power the fan and compressor. Its operating cost is to 75 % less than natural or liquid propane gas, 5% less than oil, 70% less than electric heaters making the Aquatch Heat and Cool Pumps the most economical way to heat and cool your pool. Unlike any other unit, AQUATECH are the most reliable and robust Heat pumps available in the market today, which are designe d and built by qualifie d and professional engineers with the combined experience of over 0 years. As a result, we can offer an alternativ e over traditiona l choices for heating and cooling solution s for pools. We have develope d a single source for not only manufacturing Heat pumps, but for providing design, maintenance, consultanc y, installatio n and specialize d service s require d to guarantee the results you demand. So on your next project, let us help in achieving the right heating and cooling solutions.

How Does The AQUATECH Heat Pump Work? The AQUATEC H heat pump utilize s proven refrigeran t technology to capture latent heat from the ambient air and transfer it to the pool water.

EVAPORATOR CONDENSER COIL Expansion Device Low temperature, Low Pressure Vapour Compressor Heat Exchanger Refrigerant is used because of its ability to absorb and transfer heat energy.

3 How Does The AQUATECH Heat Pump Work? The AQUATEC H heat pump utilize s proven refrigeran t technology to capture latent heat from the ambient air and transfer it to the pool water. This is accomplishe d by utilizin g minimal amounts of electricity and Refrigerant, along with a high performance fan, super-efficient compressor and your already existing pool pump. EVAPORATOR CONDENSER COIL Expansion Device Low temperature, Low Pressure Vapour Compressor Heat Exchanger Refrigerant is used because of its ability to absorb and transfer heat energy. The fan draws large quantities of warm air through the evaporator coil that acts as a heat collector. The liquid refrigerant inside the evaporator coil absorbs the free ambient heat from the drawn-i n air, changing the liquid refrigerant into gas. Water inlet (Cold) Water outlet (warm) high temperature, high pressure Super heated vapour The refrigerant gas is then passed through the compressor. The compressor compresses the refrigerant gas to increase its pressure and temperature. This super heated gas is then pumped to the heat exchanger condenser. High temp, high press. Condenser The heat exchange r then transfer s the heat from the compressed gas to the incoming pool water thus increasing the pool water temperature. The refrigerant gas condenses Pressure (Mpa) Expansion device Low temp, Low press. Evaporator Effective latent heat Compressor back into a liquid state and is pumped through the system back to the evaporator coil to repeat the cycle. Enthalpy (kj/kg) As with all swimming pool heating systems, you are advised to use a pool cover when the pool is not in use. This will keep evaporation, the greatest heat loss, to a minimum, and so reduce the overall pool heating costs and unwanted frustrations. If no cover is used it is essential that the heat pump be oversized accordingly. How Efficient is it? The efficiency of the heat pump is measured by the coefficient of performance (C.O.P.) -i.e. the ratio of energy input to energy output. This is dependant on the ambient air temperature and the temperature of the water of the swimming pool. For every unit of electricity AQUATECH uses, it produces to 6 units of heat, extracted from the ambient air.

Both intranet/internet remote connection and modem connection are available via RJ5 ethernet port or via RS serial port. XWEB0 is compatible with WIRELESS COOL modules. These radio-connected modules avoid RS85 wiring and can reduce installation costs dramatically HEAT LOSSES IN A POOL Characteristics of pool use are of prime importance in sizing the water heater. Sizing should be based on four considerations.. Conduction through the pool walls. Convection from the pool surface. Radiation from the pool surface. Evaporation from the pool surface Except in the above ground pool and in rare cases where cold groundwater flows past the pool walls, conduction losses are small and can be ignored. Because convection losses depend on temperature differentials and wind speed, these losses can be greatly reduced by the installation of windbreaks such as hedges, solid fences or buildings. Radiation losses occur when then pool surface is subjected to temperature differentials: these frequently occur on clear, cool nights. During the daytime, however, an unshaded pool will receive a large amount of radiation energy. These losses and gains may offset each other. An easy method of controlling nighttime radiation losses is to use a floating pool cover, this also reduces evaporative losses. Evaporative losses constitute the greatest loss from the pool - -60% in most cases. If it is possible to cut evaporative losses drastically, the heating requirement of the pool may be cut by as much as %. The floating pool cover can accomplish this reduction.
