How does the psychrometric processes affect the conditioning of air?
a psychrometric process that involves the simultaneous increase in both the dry bulb temperature and humidity ratio of the air. a psychrometric process that involves the removal of water from the air as the air temperature falls below the dew- point temperature.
Which type of chart is used in air conditioning system?
Psychrometric chart is one of the chart that is commonly used in solving HVAC problems. The properties of air such as wet bulb temperature, dry bulb temperature, dew point temperature, relative humidity, humidity ratio, specific enthalphy and specific volume are shown on this chart.
What is air conditioning process?
In its most basic description, the air conditioning process involves two actions that occur simultaneously, one inside the home and one outside the home. Inside the home (sometimes referred to as the “cold side” of the system), warm indoor air is cooled as it blows across a cold cooling coil full of refrigerant.
What are the process of psychrometric chart?
A Psychrometric chart graphically represents the thermodynamic properties of moist air. Standard psychrometric charts are bounded by the dry-bulb temperature line (abscissa) and the vapour pressure or humidity ratio (ordinate). The Left Hand Side of the psychrometric chart is bounded by the saturation line.
Is air conditioning an adiabatic process?
Other common applications of adiabatic cooling devices include: Greenhouse temperature regulation. Residential air-conditioning.
What are the processes in the psychrometric chart?
The dehumidification process maintains air at its dry bulb (DB) temperature constant while removing moisture. This process is represented on a psychrometric chart by drawing a straight vertical line that starts at the initial relative humidity value and extends downward to the ending relative humidity.
What are different psychrometric processes?
Psychrometric processes – sensible heating, sensible cooling, humidification, dehumidification and mixing of air. It is necessary to carry out various processes on air in order to get the required quality of air.
What psychrometric process is used in winter ac?
(b) Heating and Humidification Process: The process has practical application in winter air conditioning. During this process (i) specific humidity, dry bulb temperature, wet bulb temperature, dew point temperature and enthalpy increase and (ii) RH may increase or decrease.
What are the different types of psychrometric process?

- Sensible Heat Factor (SHF)
- Heating and Humidification.
- Cooling and Humidification.
What are the different method of air conditioning?
The most common air conditioning systems include window air conditioners, portable air conditioners, wall hung split or multi head split systems, and ducted air conditioners. There is a wide variation in the quality and features of each air conditioner, even within its own class.
What is psychrometric chart in HVAC?
Psychrometric chart is one of the chart that is commonly used in solving HVAC problems. The properties of air such as wet bulb temperature, dry bulb temperature, dew point temperature, relative humidity, humidity ratio, specific enthalphy and specific volume are shown on this chart.
How are processes represented on a psychrometric chart?
In this tutorial, we will discuss these processes and how they are represented on a psychrometric chart. On a psychrometric chart, a process, or change in properties of air, can be represented by drawing a line from the entering condition to the leaving condition. The first process that we will look at is sensible heat change.
How do you measure the psychrometric state of air?
Many variables can be measured to determine the psychrometric state of air, but dry-bulb temperature, wet-bulb temperature, dew point temperature, and relative humidity are most commonly measured. Measuring Dry Bulb Temperature
How do you show heating and humidification on a psychrometric chart?
On psychrometric chart, this process is shown as a line sloping upward and to the right. The heating and humidification of the air is best considered by looking at the two processes sequentially.
