Embodiments of the present disclosure provide an array of modularized circuits that work individually but collectively to provide a system that can manage an indoor environment. The system is designed in order to match the delivered load more closely to the required load then has been done in the past. The system is also designed in order to enhance and ease of serviceability of the individual circuits when needed.

An HVAC system having an airflow path, a primary heat exchanger disposed along the airflow path, wherein the airflow path at least partially passes through the primary heat exchanger, and a multipurpose cabinet selectively configurable between at least a first configuration for housing a first type of auxiliary heat transfer component and a second configuration for housing a second type of auxiliary heat transfer component, wherein the airflow path at least partially passes through the multipurpose cabinet.

A system for supplementing the heater for a swimming pool comprises the use of a heat exchanger for the heat generated by an air conditioning evaporator or condenser. The system can also recover and use the otherwise lost heat of an attic and redirect the same to augment the heating of the water of a swimming pool.

A dehumidifying system includes an enclosure having at least one opening disposed at a first end and at least one opening disposed at a second end. A plurality of air paths that extend through the enclosure and are separated from one another by partitions along at least a portion of the enclosure. A dehumidifier evaporator is disposed within the enclosure and configured such that at least one of the air paths is disposed to flow through the dehumidifier evaporator. The dehumidifier evaporator includes a dehumidifying coil and a heat pipe assembly at least partially wrapping around the dehumidification coil.

A refrigeration system, when a set evaporator water outlet temperature T.sub.o is less than a daily minimum temperature T.sub.min, starts a cold water unit to cool a cooling pool; when the set evaporator water outlet temperature T.sub.o is greater than a daily maximum temperature T.sub.max, starts a natural cooling source to cool the cooling pool; when T.sub.min≤T.sub.o≤T.sub.max, if T.sub.i≥T.sub.o−a set value, starts the cold water unit to cool the cooling pool, and if T.sub.i<T.sub.o−the set value, starts the natural cooling source to cool the cooling pool. The refrigeration system not only satisfies the cooling requirements of the cooling pool, but also achieves the purpose of saving energy, reducing costs.

The present invention provides improved dehumidification and/or air conditioning systems, and associated methods and equipment, for example for use in a natatorium housing a swimming pool, or other buildings which may enclose sources of humidity or otherwise resulting in a need for air treatment.

A swimming pool heating system, including a heat pump and control of the compressor of the heat pump according to a number of non-zero power levels, is detailed. The system includes, for example, three power levels, the first level being close to 40% of the maximum compressor speed, the second level being close to 70% of the maximum compressor speed, and the third level being close to 100% of the maximum compressor speed.
