Breathe Safe !!!

Indoor air pollution is a very real and dangerous thing because indoor air is far more concentrated with pollutants than outdoor air. Indoor air pollution has a far greater impact on developing countries than it does on developed ones because fuel, such as wood, charcoal and animal dung, is burned inside homes for cooking and heating. Rarely is there proper ventilation to allow the pollutants to escape, so residents of these homes end up breathing in carbon monoxide and other dangerous contaminants.

Indoor air pollutants from indoor fuel burning lead to serious human health problems, such as pneumonia, bronchitis, cancer, heart disease and asthma. And, since more than half of the population of developing nations has no other method for cooking and heating, it's not surprising that indoor air pollution from indoor fuel burning kills 1.6 million people each year.

Source Control

Usually the most effective way to improve indoor air quality is to eliminate individual sources of pollution by implementing  HVAC (Heating, ventilation, and air conditioning) system

Commonly HVAC systems control the ambient environment (temperature, humidity, air flow, and air filtering) and must be planned for and operated along with other data center components such as computing hardware, cabling, data storage, fire protection, physical security systems and power in IT industry, similarly for Hospital ICU, NICU, OT and in Pharma (Clean room) or Drugs manufacturing area or In chemical / hazardous places.

Variable Refrigerant Flow (VRF) Systems!!!

A Variable Refrigerant Flow (VRF) heating and air conditioning system is a specific type of HVAC system which utilizes one outdoor unit that connects to multiple indoor units.  These indoor units can be single systems; serving one space, or a ducted system; serving multiple spaces.  The indoor units are controlled individually by a room thermostat in a variable flow mode, while the outdoor unit provides the refrigerant. This provides for the heating and/or cooling of the individual interior space.  The outdoor units can be either air cooled or water cooled and the indoor units are connected to the outdoor unit via refrigerant piping.
A VRF system is an air conditioning/heating system where multiple indoor units can be connected, via refrigerant piping, to a single outdoor unit.  There are two types of systems:  Heat Pump and Heat Pump with Heat Recovery.  The heat pump system operates similarly to a standard heat pump where the outdoor unit is either in the heating or cooling mode and all indoor units are operating in the same (heating or cooling) mode.  The heat recovery heat pump system allows the individual space connected indoor units to be in either the heating or cooling mode whilst not requiring the outdoor unit selecting the mode.  This, is accomplished by piping refrigerant from the outdoor unit to a distribution box (circuit controller, branch selection box, etc.) and then routed using a second set of refrigerant pipes to each individual indoor unit.  This allows diversification in the overall cooling and/or heating load and greatly increases energy efficiency.
While a conventional HVAC system has outside ventilation air as part of the packaged system, VRF systems, although generally having outside air capability, usually require a dedicated outdoor air system (DOAS) to operate in conjunction with the VRF to provide ventilation air to the occupied spaces where the VRF provides the heating and cooling and the DOAS provides for the ventilation.  The DOAS only provides for the ventilation required by code thus the air side capacity of the system is not as great as a conventional all-air system which is providing ventilation air as well as enough air to be heated and cooled to satisfy the temperature control of the space.  Most VRF manufacturers do offer DOAS equipment which integrates into the control system for the VRF.

Advantages of VRF Systems

• Heat Recovery systems can be very energy efficient.
• VRF systems (per current code) can be exempt from the economizer code requirements.
• Minimal ceiling space or minimal space inside the building is required.
• Very effective in remodel projects.
