Abstract
Abstract A dehumidifying system for use in a building housing a swimming pool. The system includes a refrigerant compressor, a dehumidifier coil for dehumidifying air within the building, an air cooled condenser for reheating the air previously cooled down in the dehumidifying coil as well as for heating the swimming pool enclosure and a water cooled condenser for heating the pool water. The heat developed in the system can be used to selectively heat the dehumidified air within the building and the water in the swimming pool. The water obtained during dehumidification of the air is collected and returned to the swimming pool.

Total Claims: 4
Claim 1
Independent Claim
158 words
A dehumidifying system for use in a building housing a swimming pool, the system comprising a refrigerant compressor, a pool water heater, an air heater, and a dehumidifying coil, means for directing refrigerant from the compressor in sequence to the pool water heater, the air heater, the dehumidifying coil, and back to the compressor; means for directing air in the building, in sequence, over the dehumidifying coil and then over the air heater, and means for circulating water from the swimming pool to the pool water heater and back to the swimming pool; said system further including means to selectively by-pass the air heater with refrigerant; means to selectively by-pass the pool water heater with pool water; means in the air directing means to selectively by-pass the dehumidifying coil with some of the air passing through the air directing means, and means for returning the moisture taken out of the air by the dehumidifying coil to the pool.
Claim 2
Dependent Claim

A dehumidifying system for use in a building housing a swimming pool, the system comprising a refrigerant compressor, a pool water heater, an air heater, and a dehumidifying coil, means for directing refrigerant from the compressor in sequence to the pool water heater, the air heater, the dehumidifying coil, and back to the compressor; means for directing air in the building, in sequence, over the dehumidifying coil and then over the air heater, and means for circulating water from the swimming pool to the pool water heater and back to the swimming pool; said system further including means to selectively by-pass the air heater with refrigerant; means to selectively by-pass the pool water heater with pool water; means in the air directing means to selectively by-pass the dehumidifying coil with some of the air passing through the air directing means, and means for returning the moisture taken out of the air by the dehumidifying coil to the pool.
Claim 3
Dependent Claim
163 words
A dehumidifying system for use in a building housing a swimming pool, the system comprising a refrigerant compressor, a pool water heater, an air heater, and a dehumidifying coil, means for directing refrigerant from the compressor in sequence to the pool water heater, the air heater, the dehumidifying coil, and back to the compressor; means for directing air in the building, in sequence, over the dehumidifying coil and then over the air heater, and means for circulating water from the swimming pool to the pool water heater and back to the swimming pool; said system further including means to selectively by-pass the air heater with refrigerant; means to selectively by-pass the pool water heater with pool water; means in the air directing means to selectively by-pass the dehumidifying coil with some of the air passing through the air directing means; means adjacent the pool water heater for extracting excess heat from the refrigerant, and means outside the building for dissipating the excess heat.
