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 internal overload protection,
and operate on ________ V, ________ ph, 60 Hz power. Motors shall be 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 450 psig (3102
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 psig (2758
kPa).
