In the previous articles, we talked about the HVAC system. In short, Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation, as HVAC & R or HVACR or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).
Now we are going to examine the components of HVAC system. Join us.
HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken. read more
Heat generator is the key member of HVAC system components when it comes to heating. What happens in these devices is the generation of heat, for instance, through extraction of fuel energy inside a furnace, aka combustion chamber. Hot flue gases will then provide heating for the air or another fluid such as water that will later heat the air entering the conditioned environment. Electric heat generation could also be used to heat the conditioning air.
This work will include replacement of two existing rooftop packaged HVAC units, HVAC-ACU-209024 and HVAC-ACU-209025, located on the 773-A D-Wing roof. The DAE has requested that these units be replaced due to extensive maintenance history, repair and expense. The units will be replaced with equivalent like-for-like packaged HVAC units.

Katadata.co.id - The ministry of Commerce officially suing the European Union to the World Trade Organization (WTO) related to the discrimination of the Indonesian palm oil.
The policy is considered discriminatory because it restricts the market access of palm oil and biofuel from Indonesia.
That decision has also been through a process of scientific review and consultation with stakeholders in the palm oil sector and its derivatives.

Director General of Foreign Trade Indrasari Wisnu Wardhana mention policy RED II requires the European Union to use fuel from renewable energy from 2020 to 2030.
Then in the rules of the derivatives, Delegated Regulation, palm oil is categorized as Indirect Land Use Change (ILUC) high risk.
