What is the difference between sensible and total cooling capacity?
It also explains why the terms ‘total capacity’ (sensible & latent heat) and ‘sensible capacity’ are used to define a unit’s cooling capacity. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
What is the difference between sensible and latent cooling?
Sensible heat causes change in temperature due to contact with colder or warmer air of surfaces. Latent heat is the energy absorbed by or released from a substance during a phase change from a gas to a liquid or a solid or vice versa.
What is sensible coil load?
The sensible cooling load is a measurement of the amount of energy that must be removed from, for example, the air inside a building, in order to maintain a certain temperature, regardless of the temperature outside.
How do you calculate sensible heat load?
We also learned that the sensible cooling load (hs) is calculated by multiplying the specific heat of air (cp) by the density of air (rho) by the air flow (q) and the temperature differential. SHR is calculated by dividing sensible cooling load by the total cooling load.
What is the difference between sensible and non Sensible heat?
What is the difference between sensible and non sensible heat? Sensible heat is heat that is gained or loss measured by a thermometer or other device. Non sensible is heat that is loss during water freezing is not able to be measure by a thermometer.
What is difference between sensible and latent heat?
The main difference between the sensible and latent heat is that: Sensible heat relates to the change in temperature of an object or gas without a change in the phase. But, latent heat relates to the change in phase between solids, liquids, and gases.
What is the difference between sensible and non sensible heat?
What happens in sensible cooling?
Sensible cooling is the removal of heat from the air without changing the moisture content. On the psychrometric chart (right), the cooling process moves from right to left in a horizontal line. This process does not change the humidity ratio (W) or dew point (DP) temperature of the air.
What is the value of sensible heat given out by the coil?
What is the value of sensible heat given out by the coil? Explanation: Sensible heat given out by the coil is the product of overall heat transfer coefficient, the surface area of the coil and logarithmic mean temperature difference. So, Sensible heat = U Ac tm. 5.
What is sensible heating and sensible cooling?
For example, in a cooling system condensation forms due to removal of latent heat, and the refrigerant (cooling liquid) changes temperature due to sensible heat. The heat that changes the temperature is sensible heat, the heat that changes the phase is latent heat.
What is the difference between total heat and sensible heat?
Sensible heat is the heat that causes an object to change temperature. However, latent heat does not affect the temperature of a substance or object. Water for example boils at 100°C and the latent heat keeps the water boiling. Total capacity in an air conditioner is the sum of the sensible and latent heat values.
What is difference between sensible heat and latent heat?
How is the airflow size calculated in a Hap system?
HAP calculates required space, zone and system airflow rates. Calculations are tailored to the specific system type. Airflow sizing calculations can be based on design values of supply temperature, CFM or CFM/sqft.
What is hourly analysis Program (HAP)?
Hourly Analysis Program (HAP) Powerful tools for design and analysis. HAP is designed for consulting engineers, design/build contractors, HVAC contractors, facility engineers and other professionals involved in the design and analysis of commercial building HVAC systems.
What is the purpose of the haphap tool?
HAP is designed for consulting engineers, design/build contractors, HVAC contractors, facility engineers and other professionals involved in the design and analysis of commercial building HVAC systems. In addition, HAP’s 8760 hour energy analysis capabilities are very useful for green building design.
What types of projects can be handled by a Hap system?
HAP can easily handle projects involving: Small to large commercial buildings; Systems including rooftops, central air handlers, WSHPs, GSHPs, fan coils, VRF, chilled water and hot water plants and more; Many types of constant volume and VAV system controls;
