📋 Overview
The CH-HRV5K is a ventilation system with energy-recovery (a supply-and-exhaust unit) from the brand Cooper & Hunter. It is designed to bring fresh air into the space while simultaneously exhausting stale air — recovering a large portion of the heat from the outgoing air to pre-warm (or pre-cool) the incoming air.
This helps improve indoor air quality without large heat losses, especially important in well-insulated buildings.

🔧 Key Specifications
Here are some of the main technical parameters found in the service manual for CH-HRV5K:
Airflow (High / Medium / Low): ~ 500 / 380 / 300 m³/h.
External static pressure: ~ 100 / 80 / 60 Pa for H/M/L respectively.
Temperature-exchange (heat recovery) efficiency: ~ 68-70% at H speed (and slightly higher maybe at L) for this model.
Enthalpy exchange (heat + moisture) efficiency: Heating ~62-64% (H speed) / Cooling ~57-59%.
Mains power supply: 220-240 V ~50 Hz.
Power consumption (approximately): ~ 262 W (at H speed) according to one listing.
Acoustic – Sound pressure level: roughly ~39 dB(A) at H speed.
Physical dimensions: ~ 800 × 306 × 879 mm (W × D × H) for this model as per one source.
Weight: ~45 kg (net) according to manual.

✅ Features & Highlights
Two-way ventilation (fresh air intake + stale air exhaust) with energy recovery.
Helps maintain indoor air quality while reducing heat losses through ventilation.
Equipped with filter(s) to clean incoming fresh air.
Low-noise fan design: for example, sound pressure ~39 dB(A) at high speed for CH-HRV5K.
Designed for typical building ventilation – mid size, with ~500 m³/h flow capacity.
Static pressure allowance (~100 Pa) means it can cope with moderate ductwork resistance.

⚠️ Considerations
The actual efficiency of heat recovery depends on many factors (outdoor vs indoor temperature, humidity, filter cleanliness).
If your duct run has very high resistance (pressure drops significantly) you’ll need to check that the unit still delivers needed airflow at that static pressure.
Maintenance is required: filters need cleaning/replacement periodically, and the heat-exchange core should be inspected.
Proper installation (duct insulation, condensation drainage, correct duct layout) is vital to get the claimed performance.
The area that this unit serves depends a lot on room volume, air change rate, ceiling height, building tightness, etc. For 500 m³/h capacity, approximate suitable area might be in the range ~80-120 m² depending on usage (very rough estimate).
