Cooling Mode Operation See Fig | Carrier 38AQS008 specification

5.Remove crankcase heater from compressor base.

6.Remove compressor holddown bolts and lift compres- sor off basepan.

7.Remove compressor from unit.

8.Clean system. Add new liquid line ﬁlter drier (biﬂow type).

9.Install new compressor and position in unit. Connect suc- tion and discharge lines to compressor. Connect high pres- sure switch. Ensure that compressor holddown bolts are in place. Connect wiring. Install crankcase heater.

10.Evacuate and recharge unit.

11.Restore unit power.

Cooling Mode Operation — See Fig. 16.

1.Hot refrigerant gas from compressor ﬂows through the reversing valve and is directed to the outdoor coil vapor header.

2.Once at the outdoor coil vapor header, hot refrigerant gas ﬂows up to check valve ″A,″ which is closed. All refrig- erant is then directed to complete a path through the lower 6 coil circuits (6 passes in each circuit).

3.Refrigerant ﬂows through from the liquid header side out- lets into the transfer header, where it ﬂows upward.

4.Refrigerant leaves the transfer header through side con- nections in 4 locations and enters the middle coil circuits (4 coil circuits above check valve ″A″).

5.Refrigerant leaves the 4 middle coil circuit and enters the top portion of vapor header. The refrigerant moves up to the top 2 remaining coil circuits, where it enters the sub- cooler section.

6.Subcooled refrigerant leaves the coil circuits through the side outlets. It passes through check valve ″B″ into the system liquid line and then into the indoor coil.

7.Liquid refrigerant is expanded and evaporated to a low- pressure vapor in the indoor coil. Refrigerant vapor then returns to the outdoor unit through the system vapor line, where it is drawn through the reversing valve and accu- mulator and back to the compressor suction connection.

Heating Mode Operation — See Fig. 17.

1.Hot gas from compressor ﬂows through the reversing valve and is directed to the system vapor line and indoor coil vapor header (not shown). Refrigerant is condensed and subcooled in the indoor coil and returns to the outdoor unit through the system liquid line.

2.Check valve ″B″ is closed and all liquid refrigerant enters the liquid header.

3.Refrigerant leaves the liquid header through 12 loca- tions. It is then expanded in ﬁxed oriﬁce metering de- vices contained within the outlet tubes.

4.Refrigerant evaporates to low pressure vapor as it com- pletes its passage through the 12 parallel coil circuits (6 passes each).

5.Refrigerant moves from the coil circuits into the vapor header, where it is drawn through the reversing valve and accumulator and back to compressor suction connection.

38AQS008 specifications

The Carrier 38AQS008 is a high-performance air conditioning unit that stands out for its innovative technology, design, and efficiency. As part of Carrier's extensive line of HVAC solutions, this model is engineered to deliver optimal indoor comfort while minimizing energy consumption.

One of the main features of the Carrier 38AQS008 is its high SEER rating, which signifies exceptional energy efficiency. This rating ensures that consumers can enjoy lower utility bills and reduced environmental impact, making it an ideal choice for eco-conscious homeowners. The unit's advanced cooling technologies work seamlessly to maintain precise temperature control, ensuring a pleasant environment regardless of the season.

The Carrier 38AQS008 employs a variable-speed compressor, which allows the system to adjust its operation based on the cooling demand. Unlike traditional fixed-speed units that operate at a single speed, the variable-speed technology leads to quieter operation, increased efficiency, and improved dehumidification. As the unit operates at lower speeds, it can effectively reduce energy usage when full cooling capacity is not required, further enhancing overall efficiency.

In addition to its potent cooling capabilities, the Carrier 38AQS008 incorporates a robust filtration system that captures airborne particles, dust, and allergens. This feature not only improves indoor air quality but also ensures that the system operates efficiently by maintaining clean coils. Users can enjoy a healthier living space while also prolonging the lifespan of the air conditioning unit.

Another characteristic of the Carrier 38AQS008 is its durable construction, designed to withstand harsh weather conditions. The unit is equipped with a galvanized steel cabinet that offers corrosion resistance, and its compact design allows for easy installation and integration into various home environments.

Moreover, the Carrier 38AQS008 is compatible with smart home technology, allowing users to control their air conditioning system remotely. This feature enhances convenience and efficiency, as homeowners can adjust settings based on their daily routines and preferences.

Meeting rigorous energy performance standards, the Carrier 38AQS008 exemplifies Carrier's commitment to sustainability and customer satisfaction. With its combination of advanced features, reliable performance, and user-friendly technology, this air conditioning unit is a superior choice for those seeking a dependable and efficient cooling solution.
