Algae reduction device for air handler systems

Abstract

A system, and kit of parts capable of retrofit and use with an air handling system. The system includes housing and a drain pan with a raised edge. The kit includes a fluid reservoir attachable to the housing for holding fluid, a pump mounted on the fluid reservoir, and a tube to transfer the fluid from the fluid reservoir to the drain pan. The drain pan includes a drain. A tube clasp made from a single piece of material folded upon itself to define an opening for receiving the tube. The tube clasp has a spring loaded hinge. The open portion includes a flared section to enable the open portion to removeably clasp the raised edge of the drain pan. In one embodiment the pump intermittently pumps fluid into the pan to increase latency of the fluid in the pan and drain to enable the fluid to inhibit algae growth.

Description

FIELD OF THE INVENTION[0001]This invention relates generally to air handling systems, and particularly to improvements to air handling systems capable of reducing algae growth.BACKGROUND OF THE INVENTION[0002]Air handling systems are often termed air handlers or air handling units. Such air handling systems to regulate and circulate air as part of a heating, ventilating and air-conditioning (HVAC) system. Air handlers usually include metal housing containing a blower, heating or cooling elements. Residential air handlers typically include both heating and cooling elements. Commercial air handlers may be specifically designed to circulate heat in a large structure or vehicle. In some cases air handlers are mounted on a rooftop. In other cases air handlers are mounted in a basement in conjunction with the boiler or other heating device.[0003]Air handlers usually connect to a duct work ventilation system that circulates and distributes air from the air handler to within a structure.[00...

AI Technical Summary

Benefits of technology

The present invention is a system for preventing algae growth in a drain pan. The system includes a housing with a pan that captures leaks and condensate, a fluid reservoir, a pump, and a tube to transfer fluid from the reservoir to the pan. The pump is controlled to pulse the fluid during operation, which increases latency of the fluid in the pan and drain to enable it to inhibit algae growth for a longer period of time. The system utilizes gravity to draw fluid from the reservoir into the pan, reducing strain on the pump. The combination of gravity feeding and pulsed pump operation increases the pump life, reduces wear on the pump motor, and minimizes energy consumed by the pump motor. This is particularly useful in battery-powered systems. The air handler can be used to deliver heat, and the heat reduction improves pump life and reduces wear. The system design reduces heat stress on the pump and improves pump longevity.

Problems solved by technology

Corrosion is likely anywhere air changes temperature and condensation occurs.

One problem shared by manufacturers of air handlers as well as residential and commercial users of air handling systems is that condensation can lead to growth of algae and other undesirable biological life.

Algae can grow rapidly under ideal conditions and is known to clog pan drains in air handlers.

This drain can become plugged with algae when algae grow in the pan causing pan to overflow.

Pan overflow may corrode, or otherwise damage the air handler.

Nearby flooring, walls, and other surrounding structures and equipment may also be damaged.

Over time the damage can be considerable.

Puddles may be undesirably aromatic.
