A combination fence and solar heater. The fence for enclosing a swimming pool and heating water from the swimming pool in order to provide more comfortable swimming conditions and a longer swimming season. The fence includes posts, upper and lower rails, and pickets. The rails include first and second conduits, each having a passageway for carrying water being circulated in communication with the swimming pool. The first conduit has an exterior surface that is exposed to the sun; absorbing solar energy which heats the stream of water therein. The second conduit is nested within the first conduit and absorbs a portion of the energy absorbed by the first conduit. Often, water temperatures within the first and second conduits differ from each other, allowing for discharge of heated water over a range of temperatures to the swimming pool.

The aforesaid units together with the central control unit (v) constitute one system, which is the water-level controlling system (6) of a pool (m) filled with water that is mounted on a motor vehicle. On the other hand, the invention relates to an application for transportation of people in a pool (m) mounted on a motor vehicle and filled with water which vehicle is utilised as a sightseeing bus comprising the complete range of services provided by the mobile bathing vehicle, such as sightseeing tours, bachelor parties, hen nights, school trips and any function or social event.

The invention relates to a floating structure comprising pontoons (P) that are interconnected so as to form at least one closed floating frame of any geometrical shape, which is fixed to means for stabilising and anchoring in relation to a body of water, the at least one frame (n) being secured to a sealed pocket (1) to be filled with water in order to allow the movement of at least one person, said pocket (1) being fixed to a filtering system (2). The walls of the pocket (1) are provided with flexible thread-like elements (6) that have elastic means (7) for coupling both to a framework (8) that has been secured to the at least one frame and is designed to be submerged in the body of water, and also to a part of the underneath face of the pontoons (P).

A separator device for separating coils of a heat exchanger assembly has a top surface opposite a bottom surface, and an inner portion opposite an outer portion. The inner portion and the outer portion extend between the top surface and the bottom surface. The separator device further includes a pair of sides extending between the inner portion and the outer portion, each of the sides defining a concave curve having an apex. A lug is provided to connect the apex of each concave curve. At least one ramp is defined on the top surface and/or the bottom surface, extending from the inner portion toward the lug. The lug is arcuately shaped to project away from the top surface and the bottom surface and is shaped to correspond to a gap between adjacent coils of the heat exchanger assembly.

Systems and methods for passive and active hybrid defrost control for a pool/spa heat pump are provided. The system monitors the temperature of the evaporator coil of the heat pump and, as required, operates the heat pump in a passive defrost mode if the temperature is less than or equal to a first predetermined temperature value. The system operates the heat pump in an active defrost mode if the temperature of the evaporator coil remains below the first predetermined temperature value and a first time period has expired. The system can stop operation of the active defrost mode when the temperature of the evaporator coil is greater than a second predetermined temperature value. Additionally, the system can stop operation of the passive defrost mode or the active defrost mode upon expiration of a timeout timer.

A swimming pool or spa heat pump operable in cooling and heating modes, along with a method of operating same is disclosed. The heat pump includes a compressor, first and second heat exchangers, refrigerant charge compensator, and at least one means for lowering the pressure of refrigerant provided to the first and second heat exchangers. The first heat exchanger is configured to transfer thermal energy to and/or extract thermal energy from a first fluid, and the second heat exchanger is configured to transfer thermal energy to and/or extract thermal energy from pool or spa water. The refrigerant charge compensator is configured to reduce an amount of active refrigerant charge in circulation in the heat pump when the heat pump is operated in the cooling mode and increase the amount of active refrigerant charge in circulation when the heat pump is operated in the heating mode.

A heat exchange assembly for heating a pool includes a housing that defines an internal space. The housing has a top that is open. A lid, which is complementary to the top and substantially transparent, is sealably couplable to the housing to cover the top. A tube is loopedly positioned in the internal space. The tube has opposing endpoints that are positioned through the housing. Each of a pair of couplers is coupled singly to the endpoints of the tube. The lid is configured to allow sunlight to pass through the lid into the internal space, wherein the internal space is heated relative to the ambient environment. The tube is configured to transfer heat from the internal space to liquid passing through the tube. The couplers are configured to couple the tube to a reservoir of liquid, such as a pool.

An accelerator used for increasing water circulation velocity through a swimming pool's filtration/heating system. It comprises one or more rigid elongated and open-ended tubular sections; one end formed at a 90-degree angle into a flange inserts into the pool vacuum intake or skimmer port. The other end may be any variety of shapes, with multiple vents or openings. When the flange end is attached to the vacuum intake, the accelerator sits parallel to the pool wall with its base close to the pool bottom. The base may have protrusions perpendicular to the body to act as feet on the wall. The accelerator can be adjusted to variable lengths with sections locking into place with male and female adapters. The accelerator's sections should have small drilled holes at intervals along their length for the safety of pool equipment and swimmers. The lowest portion of the accelerator body has a drainage hole.
