Natural Ways to Lower Humidity at Home:

Humidity plays a big role for human comfort situation. Basically we need to understand that the comfort level is combination of temperature and humidity (DBT & Rh). In tropical weather the third most important factor is air flow velocity. As the air become stagnant the humidity levels go up. A comfortable level of relative humidity range for human being is 25-60% with different temperatures.

There are some basic steps for having humidity at lower or comfort range in homes. Like,

a) Heavy / frequent use of flowing hot water for bathing or similar purpose when bathrooms are adjacent and directly opens in the home / room causes humidity increase in the home. To avoid the same try to have better ventilation / exhaust in bathrooms so that humid air from bathroom does not ex-filtrate to home / room.

b) Make necessary arrangements for the room or home to have adequate windows for fresh air circulation at the highest rate. This is the most effective way. High humid areas like kitchen, bathrooms, wash areas etc. Must be mechanically ventilated or should have enough opening area (window) for additional humid air to get escaped from the room. A closed volume / room have high tendency for humidity increase.

c) Indoor plants tend to release considerable amount of humidity to the room. Indoor plants should be kept near to the ventilation opening / window. Also one should avoid over watering these plants.

d) A certain level of humidity can be controlled by heating up the room as higher temperature air can carry more humidity (water grains). But this definitely does not provide enough comfort in hot tropical weather of India.

Above are common ways to have relief; however the efficiency of these things strongly depends on local weather conditions. For further needs, mechanical ways like AC, dehumidifier etc. will solve the purpose.

Why is your AC blowing warm air?

Domestic AC now a days split / cassette / ductable type have basically 2 units. Indoor Unit and Outdoor Unit. Many times you may find your AC is blowing warm air instead of cold. In India we have a very rare application of a heat pump or an AC with heating & cooling mode both. So it is quite obvious that if your AC is blowing hot air, something is wrong.
Instead of directly going for an external help, lets have a look at the basic reasons for the said problems:

  1. a) Check thermostat;

Sounds very funny but it is a very commonly found mistake which is always ignored to be checked. So please check the temperature settings in your thermostat with selection of cooling MODE is proper or not. Also check the location of the sensor of the thermostat. It must be in the path of air returning to your AC indoor unit or inside the room near to indoor unit.

b) Restriction in airflow:

Many times we find that ACs are not cleaned or have not under gone periodic cleaning / maintenance causing chocking of filters & coil. Since the air is not flowing at desired rate or speed in adequate quantum the cooling effect reduces and may cause up to heating illusion also. So its time to check and clean. For domestic ACs a home made cleaning may work. For institutional applications you may need a professional help.

c) No power to outdoor unit:

Many times it may happen specially in semi-urban or rural areas where power fluctuation is frequent and which may cause tripping of MCB (power supply switch) of outdoor unit. In domestic ACs it may be a situation where indoor unit is powered ON but power supply to outdoor is interrupted.

d) Some problem in compressor / Refrigerant gas in outdoor unit:

After all above basic possibilities as mentioned in point a,b,&c; we now have a possible mechanical failure in outdoor which surely needs a professional assistance for any type of AC.

  • Clean room facility as Per USFDA/WHO/UKMHRA
  • Non-Clean Utilities like Potable Water, Plant Steam, Water Pre-Treatment Systems, Non-lubricated CA systems etc.

INSTALLATION VALIDATION AND QUALIFICATION

Validation and Qualification is the process of proving and documenting that the system performs as per the design specification and the Client’s User Requirement Specification (URS).

ECS contractor entailed the following aspects:

  • Air balancing
  • Room air change rate calculations
  • Room pressurization measurements
  • Filter integrity (DOP) testing of HEPA filters
  • Room particle count testing
  • Control system software functionality tests
  • Instrument calibrations
  • Room temperature monitoring
  • Room relative humidity monitoring
  • Maintenance procedures

The Operational Qualification process verified and documented that the systems operated within the required limits and tolerances and that the systems complied with the design requirements.

 

PERFORMANCE AUDIT:  

  • General specification and compliance check.
  • HEPA filter leak test
  • Factory ducting post welding leak test
  • Room differential pressure test verification
  • Particle test for cleanliness
  • Air pattern smoke test
  • Light intensity test
  • Noise test
  • Air velocity test
  • Air temperature and RH tests
  • Room pressure gradient including the system capability to avoid decay of negative pressure.
  • All the conditions, class of cleanliness, air pressure gradients, temperature and RH and other parameter shall be ensured during the operation of the laboratory.
