PART 3 — PART 3 INDIVIDUAL SYSTEMS
3.01 AIR-COOLED
A. The indoor unit shall consist of an evaporator section including evaporator coil, blower
package, controls, electrical section, and compressor.
B. CONDENSER
1. Outdoor Propeller Fan Condenser: The outdoor condenser casing shall be made of
aluminum, and all structural supports, coil frame, motor drive supports, and mounting legs
shall be made of galvanized steel. The condenser shall have copper tubes expanded into
aluminum fins. Headers and connections shall be copper. The coil shall be pressure tested
and sealed for shipment. The condenser motors shall have permanently lubricated, sealed,
ball bearings, and internal overload protection, and operate on ________ V, ________ ph,
60 Hz power. Motors shall be 1140 RPM and mounted inside the condenser casing for
weather protection, and shall be wired to a terminal strip in a weatherproof panel on the
unit. The direct drive, aluminum fan blade and painted steel hub assembly, shall be
protected by a heavy-gauge, vinyl-coated, steel-wire fan guard. On multiple units, each
fan section shall be separated by full-width baffles to prevent bypass air. The condenser
shall be sized for ________ º F (ºC) ambient, and condensing temperature controls shall be
fan speed for -20º F (-29º C) winter ambient.A ship loose pressure relief valve shall ship
with the condenser.
2. Flooded Controls: Flooded controls shall maintain head pressure to -30º F (-34.4ºC) by
regulating the effective condensing area within the condenser coil. Controls shall ship
loose and be mounted to the side of the condenser. A ship loose pressure relief valve shall
ship with the condenser.
3.02 WATER-COOLED
A. The water-cooled system shall consist of an evaporator section including evaporator coil,
blower package, controls, electrical section, compressor, and water-cooled condenser. The
condenser shall be stainless steel brazed plate design and shall be controlled by 2-way (3-way
optional) head pressure-regulated valve. Maximum water pressure shall be 400 psi (2758 kPa).
3.03 GLYCOL-COOLED
A. The glycol-cooled system shall consist of an evaporator section including evaporator coil,
blower package, controls, electrical section, compressor, and glycol-cooled condenser. The
condenser shall be stainless steel brazed plate design and shall be controlled by 2-way (3-way
optional) head pressure-regulated valve. Maximum water pressure shall be 400 psi (2758 kPa).
