THX140WDCHAX provides 14 kW nominal cooling and 16 kW nominal heating for homes, offices and compact commercial premises. We select the outdoor unit alongside room loads, operating hours and the indoor units that will run at the same time.
Model specifications
- Configuration: Single-phase compact VRF module
- Nominal cooling capacity: 14 kW
- Nominal heating capacity: 16 kW
- Nominal cooling input power: 3.89 kW
- Nominal heating input power: 3.95 kW
- Power supply: AC 1Φ, 220–240 V / 50–60 Hz
- Maximum connected indoor units: 9 — Subject to the connection ratio and approved indoor-unit combination
- Dimensions: 770×980×360 mm
- Net weight: 71 kg
Nominal capacity describes a stated test point, rather than guaranteed output at every outdoor temperature. We check design-temperature performance, piping corrections and the simultaneous demand of the connected rooms before confirming equipment selection.
Piping, height difference and operating limits
The catalogue reference is 70 m of total piping, with the longest route to an indoor unit limited to 60 m. The reference outdoor-to-indoor height difference is 30 m, with 15 m between indoor units. The direction of the height difference and branch conditions must be checked for the selected arrangement. These limits must be satisfied together with pipe diameter, branch placement, equivalent length and additional refrigerant requirements.
- Cooling range: -5 to 59°C — Dry-bulb reference; check the model-specific conditions
- Heating range: -21 to 17°C — Outdoor wet-bulb reference
- Indoor-to-outdoor connection ratio: 50–150% — A connection allowance, not guaranteed simultaneous capacity
Compact installation without restricting airflow
The A Series provides a front-discharge outdoor-unit arrangement and front, bottom, right or rear piping options. We choose the route around real site constraints while keeping air intake, discharge and service clearances open. A small casing must still breathe correctly behind a screen or on a balcony.
Temperature limits need careful interpretation
The A Series catalogue gives cooling at −5 to 59°C dry bulb and heating at −21 to 17°C wet bulb. Cooling at 55–59°C is described as intermittent operation. The upper boundary is not a guarantee of unrestricted continuous cooling or nominal capacity at that temperature.
What we check before selection
- Room-by-room heat gains and winter heat losses
- Simultaneous loads, connection ratio and indoor-unit compatibility
- Outdoor airflow, structure, vibration and service access
- Branch arrangement, piping corrections and refrigerant charge
- Electrical supply, isolation, protection and control interfaces
Frequently asked questions
Does the maximum indoor-unit count guarantee full capacity in every room?
No. Connection count describes an allowed system arrangement. Available output depends on the outdoor unit, operating conditions and the combined demand of the rooms. We check both the count and capacity ratio before approving the combination.
Can I use these limits directly as an installation design?
The values support preliminary comparison. The final design also requires the exact model documentation, load calculation, branch and pipe selection, electrical coordination and commissioning procedure.
