L— Liquid Line S — Suction Line

NOTES:

1.Shading indicates double suction riser required on units if con- densing unit is located higher than evaporator.

2.Pipe sizes are based on an equivalent length equal to the max- imum length of interconnecting piping, shown for each column, plus 50% for fittings. Example: Equivalent length = Maximum linear length x 1.5.

3.Suction and liquid line sizing is based on pressure drop equiva- lent to 2 F (1.1 C) at nominal rating conditions.

4.All pipe sizes are OD inches. Equivalent sizes in millimeters follow:

38APS025-050, 38APD025-100 specifications

The Carrier 38APD025-100 and 38APS025-050 are advanced air conditioning units designed to optimize comfort and efficiency for residential and commercial spaces. Both models integrate cutting-edge technology with user-friendly features, making them a popular choice among HVAC professionals and homeowners alike.

The Carrier 38APD025-100 is a 2-ton air conditioning unit that boasts a Seasonal Energy Efficiency Ratio (SEER) rating of 16. This high SEER rating indicates energy savings and lower operating costs, an essential factor for environmentally conscious consumers. Its compact design allows for easy installation in various spaces, while the durable construction ensures longevity and reliability.

On the other hand, the Carrier 38APS025-050 is a 2.5-ton model known for its efficient cooling capabilities and versatile features. With a SEER rating that reaches up to 17, this model also emphasizes energy conservation without sacrificing performance. The 38APS025-050 is particularly suited for larger spaces or applications requiring more cooling capacity.

Both units incorporate Carrier's innovative technology, including the Inverter Compressor System. This technology adjusts the compressor's speed based on the required cooling demand, leading to quieter operation and reduced energy consumption. Additionally, both models feature two-stage cooling to enhance comfort and humidity control, ensuring a consistent indoor climate.

The units are equipped with advanced filtration systems that improve indoor air quality by capturing dust, pollen, and other airborne particles. This is particularly beneficial for allergy sufferers, as it helps to create a healthier living environment.

Another key characteristic of these models is their compatibility with smart thermostats and home automation systems. Users can control their air conditioning units remotely, setting schedules, adjusting temperatures, and monitoring energy usage via mobile apps. This smart technology not only enhances convenience but also contributes to energy savings.

In summary, the Carrier 38APD025-100 and 38APS025-050 stand out in the market for their impressive efficiency, advanced technology, and user-friendly features. They represent a blend of performance and comfort, making them an ideal choice for anyone looking to invest in a reliable and energy-efficient air conditioning solution. Whether for a home or a commercial application, these models deliver quality and value.
