A particulate catch basin device for a condensate drain line used with an air conditioning system is described. The device includes a detachable water container in which solid particulates are captured. The detachable water container is connected to a head apparatus to which a condensate water line is attached. Water inside the detachable water container operates as a trap to capture particulates contained in condensate water entering into the device from an air handler through the condensate water line. Water, with the particulates removed by their capture within the detachable water container, flows out of the device through a connected drain pipe. A maximum water height within the detachable water container and head should not exceed a point that is lower than a lowest point of entry into the drain pipe. The device can include transparent materials to facilitate monitoring of the accumulation of particulates within the detachable water container.

An HVAC condensate evaporation system or aerobic dispersion system may transform the condensate that drains out of HVAC systems and/or septic systems into steam that is less likely to cause property damage. The system may be installed midstream in a condensate line and condensate that flows through the condensate line in normal operation may enter the chamber where it hits a solar-powered boiler that evaporates the condensate back into the atmosphere as steam. By converting the condensate into steam, property damage due to drainage out of the condensate line of an HVAC system may be minimized, or even eliminated. The system also may include a back-up capacitor or battery for low solar days. The system may further include wireless notification capability, including, but not limited to, Wi-Fi capability, to transmit notifications to the building owner or other interested parties of condensate issues as they may arise.

An air-conditioner unit comprising: a temperature regulation unit having an evaporator; a condensate filtration unit arranged to receive a condensate from the evaporator, and operable to filter the condensate; wherein the air-conditioner unit comprises a controller to operate the condensate filtration unit between a plurality of purging states, the plurality of purging states comprises a first purging state wherein the condensate is purged bypassing the condensate filter unit and a second purging state wherein filtered condensate is purged.

A system and method for removing unwanted particles and pathogens, including but not limited to viruses, from a volume of gas. The system exhibits low resistance to air flow, allowing a high volume flow and rate of gas volume to be processed. Cold surfaces reduce the temperature of incoming gas causing condensation of water from the gas. The condensate contains unwanted particles and pathogens that have been removed from the volume of gas. The condensate is caused to pass over heated surfaces that comprising a hydrophobic coating, and also comprising catalytic surfaces with anti-viral coatings to neutralize contagions. Micro-spray nozzles, which may incorporate ionization, may be utilized to spray collected water onto the heated surfaces where the contagion may be utilized. The system may comprise multiple stages. The system provides better contagion neutralization and higher flow rates than prior art systems while using less energy, and producing less noise.

An air cleaner according to an embodiment of the present invention comprises a housing including a suction portion through which external air is suctioned and a discharge portion through which the suctioned air is discharged; a filter disposed between the suction portion and the discharge portion and configured to purify the suctioned air; a gas pump connected with the discharge portion and configured to rotate so as to discharge the air purified by the filter to the discharge portion and a controller configured to control a rotation direction of the gas pump, wherein the gas pump includes a rotor including a gas pump base disk disposed in and rotatably supported by the housing, a gas pump disk array in which segment disks having an open center area are disposed on the gas pump base disk to be spaced apart from each other, and a rotor magnet installed on the gas pump base disk and a stator including a stator coil disposed in the housing and installed to face the rotor magnet.

A direct evaporative cooling system add-on to the existing air conditioning system for more effectively removing the Latent-heat-of-condensation of the refrigerant of the system greatly enhances the EER rating of the system. Upgrading the conventional air-conditioning systems from air cooled refrigerant-condensing-radiator to water-evaporative-cooling via an ADD-ON unit, comprising a reservoir that stores water to be periodically pumped up a pipe under pressure controlled by the electronic controller for timing and quantity. The water is sprinkling uniformly with the help of a plurality of holes in the pipeline wetting the condensing radiator, some of which evaporates cooling the radiator and the excess returning to the reservoir to be recycled over the radiator repeatedly allowing the evaporation and heat exchange process to continue. This cooling effect reduces the pressures required by the compressor at the same time reducing the power drawn from the electrical grid saving money on the electric bill and in turn reducing the carbon foot print created by the use of air conditioning.

A refrigerator cycle may include a condenser and an evaporator. A cross flow heat exchanger may be constructed and arranged to pass air in first and second directions and transfer energy between air in the first direction and air in the second direction. A fan may be constructed and arranged to draw air from the evaporator over the condenser and to create air flow through the cross flow heat exchanger in the first direction, past the evaporator, through the cross flow heat exchanger in the second direction, and past the condenser. The evaporator may cause water in the air to condense.

A treatment apparatus for air conditioning and refrigeration system drains includes a body portion having an inlet, outlet, upwardly extending neck portion, and downwardly-depending reservoir extending below the inlet and outlet. The apparatus is installed with the inlet and outlet interposed in air conditioning drain line. A chemical insert cartridge is installed into the central cavity of the body. The cartridge includes a shell with a plurality of openings, and contains a quantity of biocide such as one or more biocide tablets, so that the tablets dissolve through the openings in the shell when exposed to the water in the drain line. As the drain water passes through the apparatus the biocide is released into the drain water, preventing algae growth and discouraging insects and pests from occupying the drain line.

A water handling device comprising a water processing unit and an outer shell housing of vibration and/or pulsation damping material. The water handling device comprising opposed end plates including a water inlet connector, a water outlet connector, and a power connector. A circuit board extends between the opposed end plates and is connected thereto. An inner housing made of cured encapsulating material filling an interior volume defined by the outer shell housing and the end plates. The encapsulating material is hard or elastic relative to the soft outer shell housing. Vibration and/or pulsation damping elements protrude outwardly relative to the outer shell housing.

An automated primary condensate drain line chlorination system includes a first T-fitting installed in an existing municipal water supply line that contains chlorine and algaecides, a second T-fitting installed between an outlet of an existing primary condensation tray of the central air conditioning system and the existing primary condensate drain line, a water supply line extending between the T-fittings, and a normally closed solenoid valve installed in the water supply line between the T-fittings operatively connected with the electrical circuit of the thermostat and fan motor of the central air conditioning system. The solenoid valve opens automatically upon operation of the fan of the evaporator unit of the central air conditioning system to allow a small amount of water from the municipal water supply line to flow into the primary condensation tray and the primary condensate drain line to prevent the growth of algae and/or fungus therein.
