Abstract: 1280686 Air conditioning plant ITT INDUSTRIES Inc 29 July 1969 [2 Aug 1968] 38024/69 Heading B1T [Also in Divisions F4 and F3] In an air conditioning plant, a filter unit comprises fibre glass or dense foam filter mats 47 or a filter blanket passed between rollers. A warning light is actuated when the set of filter mats or the filter roll requires replacement in response respectively to a device for measuring the pressure difference between opposite sides of the mats and to a limit switch actuated near the end of the roll. A fan 53 draws air through the filter unit.

Abstract: An improved air-conditioning reheat system having a control valve responsive to the airstream temperature leaving the reheat coil for restricting refrigerant flow through one of two parallel refrigerant condensers upstream of the reheat coil when increased reheat is called for thereby flooding one condenser with liquid refrigerant and reducing the total condenser capacity to allow a combination of saturated liquid and vapor refrigerant from the other condenser to be delivered to the reheat coil serially connected between the condensers and the evaporator. The reheat coil, which functions as a liquid-to-air heat exchanger during normal operation with low reheat, then becomes a condenser to provide additional transfer capability. A bypass capillary allows a trickle of liquid refrigerant from the flooded condenser into the refrigerant flow path to prevent the flooded condenser from becoming logged with oil and to control the amount of uncondensed vapor refrigerant being fed to the reheat coil.
