PRODUCT DESIGN

This section gives a basic description of cooling unit opera- tion, its various components and their basic operation. Ensure your system is properly sized for heat gain and loss according to methods of the Air Conditioning Contractors Association (ACCA) or equivalent.

CONDENSING UNIT

These units are designed for free air discharge. Condensed air is pulled through the condenser coil by a direct drive propeller fan and then discharged from the cabinet top. The unit requires no additional resistance (i.e. duct work) and should not be added.

The GSH13, GSH14, ASH13 and VSH13 Heat Pump con- densing units are designed for 208-230 dual voltage single phase applications. The GSH13 3 ton model is available in 230V, 3 phase applications. The GSH13 4 and 5 ton models are available for 230V, 3-phase and 460V, 3-phase applica- tions.

The units range in size from 1.5 to 5-ton and have a rating of 13 and 14 SEER. SEER efficiency is dependent upon the unit and its components. Refer to the "Technical Information" manual of the unit you are servicing for further details.

The GSC13, GSC14 and ASC13 and VSC13 Condensing Units are made in 1.5 through 5 ton sizes. They are designed for 208-240 volt single phase applications. The GSC13 3 ton model is available in 230V, 3 phase applications. The GSC13 4 and 5 ton models are available for 230V, 3-phase and 460V, 3-phase applications.

Suction and Liquid Line Connections

All units come equipped with suction and liquid valves designed for connection to refrigerant-type copper. Front seating valves are factory-installed to accept the field-run copper. The total refrigerant charge needed for a normal operation is also factory-installed. For additional refrigerant line set information, refer to the "Technical Information" manual of the unit you are servicing.

Compressors

GSC13, VSC13, GSH13 and VSH13 use a mix of reciprocat- ing and scroll compressors, except for the VSC130181AA which uses a rotary compressor. The ASC13 and ASH13 use the Copeland Scroll® Compressor. There are a number of design characteristics which differentiate the scroll compres- sor from the reciprocating compressor. One is the scroll. A scroll is an involute spiral which, when matched with a mating scroll form, generates a series of crescent-shaped gas pockets between the members (see following illustration). During compression, one scroll remains stationary while the other form orbits. This motion causes the resulting gas pocket to compress and push toward the center of the scrolls. When the center is reached, the gas is discharged out a port located at the compressor center.

GSC130361D* and GSC130481AG use Bristol® BENCH- MARK™ compressors, the most advanced compressors in the industry today. The BENCHMARK™ reciprocating com- pressor can be recognized by a “J” in the fourth character of the compressor model number. Innovative mechanical de- sign and gas management make the BENCHMARK™ com- pressor very efficient and remarkably quiet. The sound content (frequency) delivers exceptional acoustical charac- teristics and the virtually round housing design is compact and also helps to reduce the overall sound and vibration.

GSC130181BA use Panasonic® rotary compressors.

COILS AND BLOWER COILS

MBR/MBE blower cabinets are designed to be used as a two- piece blower and coil combination. MBR/MBE blower sec- tions can be attached to cased evaporator coil. This two- piece arrangement allows for a variety of mix-matching possibilities providing greater flexibility. The MBE blower cabinet uses a variable speed motor that maintains a con- stant airflow with a higher duct static.

It is approved for applications with cooling coils of up to 0.8 inches W.C. external static pressure and includes a feature that allows airflow to be changed by +15%. The MBR blower cabinet uses a PSC motor. It is approved for applications with cooling coils of up to 0.5 inches W.C. external static pressure.

The MBR/MBE blower cabinets with proper coil matches can be positioned for upflow, counterflow, horizontal right or horizontal left operation. All units are constructed with R-4.2 insulation. In areas of extreme humidity (greater than 80% consistently), insulate the exterior of the blower with insula- tion having a vapor barrier equivalent to ductwork insulation, providing local codes permit.

The CAPX/CHPX coils are equipped with a thermostatic expansion valve that has a built-in internal check valve for refrigerant metering. The CACF/CAPF/CHPF coils are equipped with a fixed restrictor orifice.
