Description
Overview
This bundled product includes one TAVCI7H4R18-S outdoor unit and one TAVEM7H4R18-S indoor unit for a single-zone system. Rated capacity is 18,000 BTU cooling and 18,000 BTU/h heating. Efficiency ratings include 24.5 SEER2 and 9.0 HSPF2. Electrical supply is 208/230V, 60 Hz, 1-phase. The system uses R32 refrigerant and is designed for field piping between the indoor and outdoor sections.
Performance
Compressor design is Rotary in the outdoor section. Compressor manufacturer is Zhuhai Landa (Gree). Refrigerant metering method is Capillary. Outdoor unit moisture protection rating is IPX4. Outdoor fan airflow is rated at 2119 CFM. Indoor fan type is Cross-flow with multiple speed steps for airflow control. Indoor airflow is rated up to 589 CFM at maximum fan setting.
Smart Features
Control is supported by controller model YBE1FB1F for mode selection, setpoint control, and fan speed changes. Set temperature range is 61~86Ā°F. The indoor unit provides multiple fan speed steps to balance airflow and sound based on room conditions. System operation supports standard cooling, heating, dry, and fan modes where available on the controller. For projects that require third-party controls, confirm compatibility with the specific indoor control interface before ordering.
Comfort & Noise
Indoor sound performance spans 29ā48 dB(A) cooling (SLāSS) depending on fan setting. Outdoor sound pressure level is rated at 59 dB(A) at high fan setting. Rated dehumidifying volume is 3.8 pints per hour. Maximum indoor airflow of 589 CFM supports steady air mixing and distribution. Use the fan speed steps to reduce indoor sound levels during occupied hours while maintaining temperature control. Swing motor operation supports directional airflow control where specified.
Use Case Fit
This product supports single-zone applications where one indoor unit serves one conditioned area. Published outdoor operating range supports Cooling -20~122Ā°F, heating -22~86Ā°F. Typical use cases include residential rooms, small offices, and similar spaces that benefit from zoned control. Select equipment voltage and capacity to align with the load and the available electrical service. Maximum line length is 131.2 ft with a maximum elevation difference of 82.0 ft.
Value & Reliability
Defrost method is Automatic Defrosting to maintain heating operation when outdoor conditions require coil clearing. Outdoor components use an axial-flow fan configuration where specified for heat rejection and air movement. Coil and fan assemblies are designed around aluminum fin and copper tube heat exchangers where specified. Use the listed component model numbers to streamline replacement parts selection and service planning. Routine service access focuses on airflow-side maintenance for the indoor section and refrigerant-side components for the outdoor section.
