What makes ventilation difficult in Kochi?

Kochi faces perpetually high humidity — often 90%+ even outside monsoon season. Temperatures are moderate but the year-round latent load is extreme. Without active dehumidification, fresh air ventilation actively increases indoor humidity.

Which machine is right for Kochi?

RHP Series + MERV-13

Kochi's year-round 85–95% RH makes RHP essential. The active refrigerant circuit removes moisture from every cubic metre of incoming air before it enters your home. A standard ERV in Kochi would transfer outdoor humidity indoors, defeating the purpose of ventilation. RHP delivers dry, comfortable fresh air at 22–28°C throughout the year. AQI is relatively clean, so MERV-13 is adequate.

For Kochi we specify RHP Heat Pump ERV as the default, with MERV-13 (AQI is relatively clean) filtration. Models: RHP INA-RHP Series (ceiling or floor-standing). Model-by-model airflow, static pressure and power figures are on the spec sheets.

Typically installed in: Apartments · Villas · Premium homes · Offices · Hospitals.
Also worth considering: Revita ERV only if paired with a dedicated standalone dehumidifier

How is a system sized here?

Sizing is driven by occupancy, not floor area — CO2 comes from people, so a small crowded flat needs more air than a large empty one. ASHRAE 62.1 sets the airflow per person; that number picks the unit. Kochi then adds two local constraints: a summer peak of 28–35°C, which decides how much heat recovery is worth paying for, and humidity of 80–95% RH (year-round, often 90%+), which decides whether plain recovery is enough or whether active dehumidification is needed.

Kochi questions

What do people in Kochi ask?

Kochi sees an AQI range of roughly 50–100 through the year. Kochi faces perpetually high humidity — often 90%+ even outside monsoon season. Temperatures are moderate but the year-round latent load is extreme. Without active dehumidification, fresh air ventilation actively increases indoor humidity. That range is what sets the filter grade: we specify MERV-13 (AQI is relatively clean) here.
RHP Series + MERV-13. We recommend the RHP heat-pump energy recovery unit for Kochi. Kochi's year-round 85–95% RH makes RHP essential. The active refrigerant circuit removes moisture from every cubic metre of incoming air before it enters your home. A standard ERV in Kochi would transfer outdoor humidity indoors, defeating the purpose of ventilation. RHP delivers dry, comfortable fresh air at 22–28°C throughout the year. AQI is relatively clean, so MERV-13 is adequate.
MERV-13 (AQI is relatively clean). Filter grade follows the local AQI rather than a national default — MERV-13 handles ordinary urban particulate, while HEPA-13 is warranted where AQI regularly passes 200 or where dust and industrial sources are present. In Kochi the range is 50–100.
Yes. InAir supplies and installs across India from its Hyderabad base, and Kochi in Kerala is covered end to end — free site survey, duct design, supply, commissioning with measured airflow readings, and handover. A typical residential installation is commissioned ten to twelve days after order. Send a floor plan to sales@in-air.in and an engineer returns a sized proposal.
Sizing starts from occupancy rather than floor area, because CO₂ is produced by people. ASHRAE 62.1 gives the airflow per person; that figure sets the unit, and the Kochi summer peak of 28–35°C plus humidity of 80–95% RH (year-round, often 90%+) decides whether plain heat recovery is enough or whether active dehumidification is required.
