OPERATING DATA

Sensors — The electronic control uses 4 to 10 thermistors to sense temperatures for controlling chiller operation. See Table 2. These sensors are outlined below. See Fig. 7-10 for thermistor locations. Thermistors T1-T9 are 5 kΩ at 77 F (25 C). Thermistors T1, T2, T3-T6 and T7-T9 have different temperature versus resistance and voltage drop performance. Thermistor T10 is 10 kΩ at 77 F (25 C) and has a different tem- perature vs resistance and voltage drop performance. See Ther- mistors section on page 59 for temperature-resistance-voltage drop characteristics.

T1 — COOLER LEAVING FLUID SENSOR — This ther- mistor is located in the leaving fluid nozzle. The thermistor probe is inserted into a friction-fit well.

T2 — COOLER ENTERING FLUID SENSOR — This thermistor is located in the cooler shell in the first baffle space in close proximity to the cooler tube bundle.

T3, T4 — SATURATED CONDENSING TEMPERATURE SENSORS — These 2 thermistors are clamped to the outside of a return bend of the condenser coils.

T5, T6 — COOLER SUCTION TEMPERATURE SEN- SORS — These thermistors are located next to the refrigerant inlet in the cooler head, and are inserted into a friction-fit well. The sensor well is located directly in the refrigerant path. These thermistors are not used on units with TXVs.

T7, T8 — COMPRESSOR SUCTION GAS TEMPERA- TURE SENSORS — These thermistors are located in the lead compressor in each circuit in a suction passage after the refrig- erant has passed over the motor and is about to enter the cylin- ders. These thermistors are inserted into friction-fit wells. The sensor wells are located directly in the refrigerant path. These thermistors are not used on units with TXVs.

T9 — OUTDOOR-AIR TEMPERATURE SENSOR — Sensor T9 is an accessory sensor that is remotely mounted and used for outdoor-air temperature reset.

Air Conditioner specifications

Carrier Air Conditioners have long been synonymous with reliability and innovation in climate control. Founded by Willis Carrier, the inventor of modern air conditioning, the brand has continuously set industry standards through state-of-the-art technologies and features designed to enhance indoor comfort.

One of the standout features of Carrier air conditioners is their energy efficiency. Many models are equipped with advanced inverter technology, allowing the compressor to adjust its speed based on the cooling demand. This results in decreased energy consumption, which not only reduces utility bills but also lessens the environmental impact. Recognizing the importance of sustainable practices, Carrier has integrated eco-friendly refrigerants into their systems, further promoting energy-efficient operations.

Carrier also emphasizes user comfort through its variable speed systems. These systems maintain consistent temperatures while minimizing temperature fluctuations, ensuring an even distribution of cool air throughout the home. Additionally, many Carrier models come with advanced air filtration systems, designed to capture allergens, dust, and other particulates, thereby improving indoor air quality.

The smart technology featured in Carrier air conditioners plays a key role in modern convenience. Many units are compatible with smart home systems, allowing users to control settings remotely via smartphones or voice-activated devices. With features like programmable thermostats, users can easily set cooling schedules to match their lifestyle, ensuring comfort while maximizing energy savings.

Durability and noise reduction are also central to the Carrier brand. Many models are designed with sound-dampening features, making them some of the quietest units on the market. This is particularly advantageous for residential use, where noise can disrupt daily activities and sleep.

In terms of design, Carrier air conditioners come in various styles and capacities to suit a wide range of spaces, from compact apartment units to large central systems for sprawling homes. Their extensive warranty and service offerings further reinforce Carrier’s commitment to customer satisfaction.

In conclusion, Carrier air conditioners represent a perfect blend of cutting-edge technology, energy efficiency, and user comfort. Their emphasis on sustainability and smart features positions them as a leading choice for homeowners seeking reliable and innovative climate control solutions. Whether for cooling a small room or an entire house, Carrier remains a trusted name in air conditioning.
