A cooling system for a photovoltaic panel including micro flat heat pipes (HP) integrated with thermoelectric generators (TEG) and a cooled water reservoir for cooling the working fluid in heat pipes. The cooled water in the reservoir is pumped from the condensate pan of an air conditioner. Experimental results show that cooling system reduced the average temperature of the panel by as much as 19° C. or 25%. Further, the output power of the photovoltaic panel increased by 44% when the photovoltaic panel was used in a very hot climate (30-40° C.). An additional two watts of power was generated by the TEGs.

The HVAC On Demand Via High And Low Pressure Vortex Separation Apparatus With Rotating Spin Chamber is a novel heating and cooling system that could revolutionize the HVAC industry. The instant invention takes in ambient air, via ducted fans, and separates hot and cold air by spinning the air molecules into a self-contained vortex. Specifically, it allows the less dense hot air molecules to pass through the front of the invention while diverting the cold air molecules through a series of reversing tubes to exit the apparatus. As the main rotating spin chamber spins ambient airflow into a centrifugal vortex in one direction, the air inlet tubes are positioned in such a way that it allows the rotating spin chamber to revolve in the opposite direction of the interior vortex. This captures all mechanical energy on the inside and outside of the vortex. The apparatus takes otherwise wasted mechanical energy and converts it into additional electrical energy. The entire invention along with understanding how air separation on a molecular scale works, allows the invention to be scaled to any size and configuration for an incredibly high efficiency rate.

A kitchen air-conditioning system comprises a air-conditioning assembly and a range hood assembly; the air-conditioning assembly comprising a compressor, a first heat exchanger and a second heat exchanger which are connected with each other through a plurality of refrigerating medium pipes; and the air-conditioning assembly has a fresh air inlet and a fresh air outlet, the fresh air coming from the fresh air inlet is divided into two paths; the fresh air entering the first heat exchanger flows into the kitchen through the fresh air outlet, and the fresh air entering the air intake area cools the third heat exchanger in the range hood assembly and is then exhausted to the outside through the range hood, which is helpful to reduce the intake-air temperature of the second heat exchanger, thereby improving the energy efficiency of the air conditioner.

The cooling systems and methods of the present disclosure involve modular fluid coolers and chillers configured for optimal power and water use based on environmental conditions and client requirements. The fluid coolers include wet media, a first fluid circuit for distributing fluid across wet media, an air to fluid heat exchanger, and an air to refrigerant heat exchanger. The chillers, which are fluidly coupled to the fluid coolers via pipe cages, include a second fluid circuit in fluid communication with the air to fluid heat exchanger and a refrigerant circuit in thermal communication with the second fluid circuit and in fluid communication with the air to refrigerant heat exchanger. Pipe cages are coupled together to allow for expansion of the cooling system when additional cooling capacity is needed. The fluid coolers and chillers are configured to selectively operate in wet or dry free cooling mode, partial free cooling mode, or mechanical cooling mode.

The present disclosure relates to an air handling system which has a fan supply section for intaking warm air from a room environment, and first and second indirect evaporative cooling subsystems (IDECs) spaced apart from one another to form an air plenum and a hot aisle in communication with the air plenum. The air plenum and the hot aisle are both formed between the IDECs, with the air plenum communicating with the fan supply section to receive the warm air. The IDECs receive the warm air and cool the warm air to produce first and second cooled airflows. The system also includes spaced apart cold aisles adjacent each of the IDECs for channeling the cooled airflows into an evaporator section. The evaporator section produces a final cooled airflow which is directed back into the room environment.
