Key Features
1.5 Ton Cooling Capacity
Hot weather can make indoor spaces uncomfortable, particularly when the cooling system cannot handle the required heat load. This Haier inverter window AC has a 1.5-ton capacity and a verified cooling capacity of 5000 watts, providing the specified cooling configuration of the model.
High Ambient Cooling up to 54°C
Air conditioner performance becomes particularly important during periods of extreme outdoor heat. The HWA18-W3NB-PI is specified to support cooling at ambient temperatures of up to 54°C, helping maintain cooling operation during demanding summer conditions.
Inverter Technology
Cooling requirements do not remain constant throughout the day. The air conditioner uses inverter technology, allowing its operation to respond to changing cooling requirements rather than relying only on fixed cooling operation.
Rotary Compressor
The compressor is responsible for driving the refrigeration cycle that enables cooling. This model is equipped with a rotary compressor as part of its inverter cooling system.
Convertible Mode
Cooling needs can change with weather conditions, occupancy, and personal comfort preferences. The Convertible Mode provides flexibility for adjusting cooling operation according to changing requirements.
Multiple AC Operating Modes
A single operating setting may not address every cooling and comfort requirement. The air conditioner provides Adaptable Mode, Cool Mode, Fan Mode, Dry Mode, Timer ON/OFF Mode, Turbo Mode, Summer Chill Mode, Sleep Mode, Self Clean Mode, and Silent Mode, giving users different operating options for varying situations.
Turbo Mode
Standard cooling operation may not always be preferred when faster cooling response is required. Turbo Mode provides a dedicated operating option for situations where stronger cooling operation is needed.
Summer Chill Mode
Intense summer conditions can create greater cooling demands. Summer Chill Mode provides a dedicated operating option intended for hot-weather cooling requirements.
Sleep Mode
Cooling requirements during sleep can differ from daytime use. Sleep Mode provides a dedicated setting for nighttime operation, allowing users to select a mode specifically intended for sleeping hours.
Silent Mode
Air conditioner operating sound can be distracting during activities that require a quieter environment. Silent Mode provides a dedicated operating option for users who want reduced operational disturbance.
Dry Mode
High humidity can make indoor conditions feel uncomfortable even when the temperature is moderate. Dry Mode provides a dedicated operating option for managing moisture-related indoor comfort requirements.
Fan Mode
There may be situations where users want air circulation without selecting standard cooling operation. Fan Mode provides a separate airflow setting for such requirements.
Self Clean Mode
Internal AC maintenance can be inconvenient when dust and moisture accumulate during regular operation. Self Clean Mode provides a dedicated cleaning function intended to support internal maintenance of the air conditioner.
Micro Anti Bacterial Filter
Air circulating through an air conditioner can carry airborne particles and impurities. The Micro Anti Bacterial Filter is designed to support air filtration as air passes through the unit, addressing concerns related to unwanted airborne particles during operation.
Anti-Dust Feature
Dust can enter the air conditioning system along with circulating air. The Anti-Dust feature supports the filtration configuration of the unit and helps address dust-related concerns during everyday cooling operation.
Copper Condenser
The condenser is an important component of the air conditioner's heat-transfer system. The HWA18-W3NB-PI uses a copper condenser, supporting the heat-transfer function required for cooling operation.
100% Grooved Copper
The product is specified with 100% grooved copper as part of its construction. This copper configuration forms part of the air conditioner's cooling system and heat-transfer arrangement.
Super Anti Corrosion Protection
Air conditioner components can be exposed to environmental conditions that may contribute to corrosion. Super Anti Corrosion protection is included to address corrosion-related durability concerns.
Left/Right Automatic Swing
Fixed airflow direction can concentrate cooled air in a limited area. The left/right automatic swing function moves the louvres automatically to distribute airflow across different horizontal directions.
3 Star Energy Rating
Regular AC use can contribute significantly to household electricity consumption. This model carries a 3 Star energy efficiency rating, an ISEER value of 3.45, and a stated annual power consumption of 1123.38 kWh.
Economy Mode
Users may want a separate operating setting when energy-conscious cooling is a priority. Economy Mode provides a dedicated operational option for managing cooling use.
R32 Refrigerant
Refrigerant enables heat transfer within the air conditioning cycle. The HWA18-W3NB-PI uses R32 refrigerant as the working refrigerant in its cooling system.
Remote Control
Walking to the AC unit for every setting adjustment can interrupt rest or other activities. The included remote allows users to access supported controls from a distance, while the Dim Function provides an additional remote-controlled feature.
Integrated Display
Checking operating information can be difficult without a visible interface. The air conditioner includes a display that provides a visual interface on the unit.
Timer ON/OFF Mode
Manually switching the AC on or off at specific times can be inconvenient. Timer ON/OFF Mode provides a dedicated scheduling function for controlling operation according to the user's selected timing requirements.
Corrosion-Resistant ABS Plastic Body
The air conditioner's exterior is exposed to regular handling and environmental conditions. The model uses an ABS plastic body and is specified as corrosion resistant, supporting its physical construction and protective design.
