PRODUCT DESIGN

GPC Package Cooling Units are designed for outdoor instal- lations only in either residential or light commercial applica- tions.

The connecting ductwork (Supply and Return) can be con- nected for either horizontal or vertical airflow. In the vertical application a matching Roof Curb is recommended.

A return air filter must be installed behind the return air grille(s) or provision must be made for a filter in an accessible loca- tion within the return air duct. The minimum filter area should not be less than those sizes listed in the Specification Sec- tion. Under no circumstances should the unit be operated without return air filters.

A 3/4” PVC pipe is provided for removal of condensate water from the indoor coil In order to provide proper condensate flow, a drain trap is supplied and shipped loose inside the unit for field installation. (Do not reduce the drain line size.)

Refrigerant flow control is achieved by use of restrictor ori- fices. GPC units use the FasTest Access Fitting System with a saddle that is either soldered to the suction and liquid lines or is fastened with a locking nut to the access fitting box (core) and then screwed into the saddle. Do not re- move the core from the saddle until the refrigerant charge has been removed. Failure to do so could re- sult in property damage or personal injury.

The single phase units use permanent split capacitor (PSC) design compressors. Starting components are therefore not required for these units. A low microfarad run capacitor as- sists the compressor to start and remains in the circuit dur- ing operation.

All GPC14 units have X-13 indoor blower motors that are en- ergized by a 24V signal from the thermostat and are con- stant torque motors with very low power consumption. The X- 13 features an integral control module.

Air for condensing (cooling cycle) is drawn through the out- door coil by a propeller fan, and is discharged vertically out the top of the unit. The outdoor coil is designed for .0 static. No additional restriction (ductwork) shall be applied.

Conditioned air is drawn through the filter(s), field installed, across the coil and back into the conditioned space by the indoor blower.

GPC1424-30H41* use Copeland Reciprocating Compressors. GPC1436-60H41* use Copeland Scroll Compressors. There are a number of design characteristics which are different from the traditional reciprocating compressor.

-Due to their design Scroll Compressors are inherently more tolerant of liquid refrigerant. NOTE: Even though the compressor section of a Scroll compressor is more toler- ant of liquid refrigerant, continued floodback or flooded start conditions may wash oil from the bearing surfaces causing premature bearing failure.

-Scroll Compressors use white oil which is compatible with 3GS oil which may be used if additional oil is re- quired.

-Operating pressures and amp draws may differ from stan- dard reciprocating compressors. This information may be found in the "Cooling Performance Data" section.

R-410A specifications

Goodman Manufacturing, a well-respected name in the HVAC industry, has made significant advancements with their R-410A refrigerant technology. R-410A, a hydrofluorocarbon (HFC), has positioned itself as a superior alternative to the older R-22 refrigerant, which has been phased out due to its ozone-depleting properties. Goodman’s commitment to energy efficiency and environmental sustainability is well reflected in their use of R-410A in their air conditioning and heat pump systems.

One of the main features of Goodman’s R-410A systems is their exceptional energy efficiency. The R-410A refrigerant operates at a higher pressure than R-22, which allows for better heat transfer and improved cooling capacity. This results in reduced energy consumption and lower utility bills for consumers. Goodman’s air conditioning units designed for use with R-410A are often rated with high Seasonal Energy Efficiency Ratio (SEER) ratings, making them an eco-friendly choice for residential and commercial applications.

Another notable technology employed by Goodman is their commitment to reliable performance through advanced compressor designs. Goodman's scroll compressors are optimized for R-410A, ensuring quieter operation and reducing vibration levels. These compressors are known for their efficiency and longevity, making them a favorite among homeowners seeking dependable and durable climate control solutions.

Goodman's multi-stage cooling systems that utilize R-410A offer precise temperature control and enhanced comfort. By controlling the speed of the compressor, Goodman’s units can adjust output according to the heating or cooling demand, maximizing comfort while minimizing energy waste. This adaptability not only enhances indoor air quality but also contributes to a greener environment by using less energy.

Furthermore, Goodman incorporates high-tech diagnostic controls into their systems. These controls provide real-time performance data, allowing homeowners and technicians to monitor system status and troubleshoot issues more easily. By using R-410A combined with these innovative technologies, Goodman emphasizes reliability and user-friendly operation.

In conclusion, Goodman Manufacturing’s use of R-410A refrigerant reflects their dedication to efficiency, reliability, and environmental stewardship in HVAC solutions. The combination of advanced compressor technologies, high energy efficiency, and innovative controls solidifies Goodman’s reputation as a leader in the industry, offering homeowners and businesses the comfort and peace of mind they deserve.
