📋 Overview
The CH-HRV5KDC is a balanced supply-and-exhaust ventilation unit with heat-recovery (recuperator) from Cooper & Hunter’s KDC series (Inverter-driven fans). It is designed for medium to large residential or commercial spaces where fresh-air supply and stale-air extraction are required, and energy recovery from the exhaust air is desirable.

🔧 Key Specifications
Here are the main technical specifications found for the CH-HRV5KDC:
Maximum Airflow: 500 m³/h (≈ 143 L/s)
Temperature-recovery efficiency: ~ 75 %
Enthalpy (heat + moisture) recovery efficiency: ~ 62-67 % (varies by mode)
Noise level: ~ 30 dB(A) (at the given performance)
Duct connection diameter: Ø 200 mm for this airflow class (per manual table for CH-HRV5KDC)
Input power (approx): ~ 143 W (as per table in the manual for 500 m³/h model)
Power supply: 220 V / 1 phase / 50Hz (for this model series)
Dimensions (approx): 904 × 270 × 962 mm (W×H×D) for the 500 m³/h variant (from manual)
Weight: ~43 kg for the model 500 m³/h (table listing)

✅ Features & Highlights
High-efficiency heat recovery: the unit recovers a large share of heat from the exhaust stream, reducing heating/cooling demand for incoming air.
Inverter-controlled DC fan motors with multiple fan speeds (10 speeds) for both supply and exhaust.
Automatic summer bypass, defrost mode (for colder climates) and optional CO₂ / humidity sensors for demand-controlled ventilation.
Quiet operation: noise level as low as ~30 dB(A) in one speed, making it suitable for residential use or quiet office environments.
Flexible ducting: with Ø 200 mm ducting for the model size, and adequate static pressure allowances for moderate duct runs.
Maintenance access: unit designed with service ports, filter access, and standard electrical & control connections as per user manual.

⚠️ Application & Considerations
The unit’s ~500 m³/h capacity means it is well suited for moderately large volumes. To determine the actual room/space size it can handle, you’ll need to consider the desired air-change rate (ACH), ceiling height, building tightness and duct losses.
For spaces with high duct resistance (long duct runs, many bends, high static pressure), ensure the duct design remains within the unit’s allowable static pressure for rated flow.
Filtration, duct insulation, and correct installation are important: blocked filters, un-insulated ducts or wrong layout reduce performance and efficiency.
In the winter or colder climates, make sure any defrost or pre-heating provisions are considered (as the unit supports defrost mode).
The manual lists Ø200mm ducts for this model; later larger models use larger duct diameters. Thus, proper matching of duct and supply/extract is essential.
