Systems for controlling aspects of recreational or other environments are described. Such systems are especially, but not exclusively, useful for controlling either or both of pool or spa settings and operations and include equipment that may be connected, in any appropriate way, to personal or other computers or other components capable of accepting and processing input. Operations of the systems additionally are capable of being simulated through software.

A wireless (e.g., radio) system and method for automatic water level maintenance of, e.g., a swimming pool utilizing capacitive liquid level sensing. A reference electrode allows water level sensing independent of the water chemistry or temperature. Capacitive electrodes having areas larger than the reference electrode sense various liquid levels when the liquid covers an area of any sensing electrode equal to the area of the reference electrode. Averaging is incorporated to filter out effects of wind or other disturbances. Upon sensing a given condition, the transmitter transmits a sensed condition to a remote receiver for control of valves and pumps for changing the water level in the pool. The receiver includes safety timers for filling and emptying to protect against equipment failure or communications faults. User selectable identification allows identical such radio systems to operate within proximity to each other. Power saving features are used to extend battery life.

Methods and compositions are disclosed for treating swimming pool waters in order to remove one or more nutrients necessary for algal growth and to accelerate the breakdown of objectionable chloramines within chlorinated pool waters. The target nutrients of preference are those containing phosphorus or nitrogen. Phosphorus nutrients are preferably removed by ion-exchange with finely divided lanthanum carbonate, or by direct precipitation in the pool with liquid lanthanum chloride. Nitrogen nutrients (including, in particular, chloramines) may be removed (possibly with the aid of catalysts and in separate reactors). The same reagents used to scavenge phosphates are useful in this regard, the nitrogen being released from the pool water as a nitrogenous gas. To allow the fine lanthanum carbonates to be conveniently handled in the pool environment, they may be linked to larger carrier particles, such as those of diatomaceous earth, or they may be embedded within porous beads formed from polymers or gels. In this form the reagent can be either added to, retained within and backwashed from pool filters, or added directly to pools (with or without a flocculating agent) and sucked to waste after settling. A variety of formulations for these purposes is disclosed.

A water purification system and method suitable for use in swimming pools, spas, hot tubs, water storage tanks, wells and water cooling towers employs a galvanic cell having a silver or copper or zinc anode electrically connected to a cathode made from a metal of still higher electrochemical potential, normally a platinum group metal and preferably palladium. A galvanic cell of some tens of square centimeters in size and some hundreds of grams in weight liberates sufficient silver or copper ions so as to treat a multi-thousand liter body of water, such as a swimming pool, for, typically under normal contamination, some months until the anode is consumed. Copper and/or silver ions liberated from the galvanic cell suppress bacterial, fungal and/or algae growth, thus, significantly reducing the amount of chlorine, bromine or other chemicals needed to maintain water quality. The invention operates on the current generated by the galvanic action between the dissimilar metals of the anode and cathode, and does not require external electrical power.

A system is disclosed which utilizes air conditioning waste to heat a second fluid such as swimming pool water. The second condenser for pool water heating is connected in parallel with the air conditioning condenser. An accumulator is connected between the condensers and the expansion valve to absorb fluctuations in refrigerant level due to different operating conditions caused by the pool water heating, thereby ensuring that liquid refrigerant is always supplied to the expansion valve. A controller reads the ambient air temperature at the air conditioning condenser and reads the air conditioning system condensing pressure and uses an algorithm to compute ambient air fan speed at the air conditioning condenser based on these two inputs to maintain a consistent heated pool water temperature.

An alternate system includes first and second condensers connected in series with an accumulator connected between the second condenser and the expansion valve and a pressure equalization line connected between the compressor and the accumulator. A controller reads the ambient air temperature at the air conditioning condenser and reads the air conditioning system condensing pressure and uses an algorithm to compute ambient air fan speed at the air conditioning condenser based on these two inputs to maintain a consistent heated pool water temperature.
