An air conditioning unit delivers 8.24 m3/s of air at 15.2°C DB and 85% RH to maintain 26.5°C DB and 50% RH room conditioned. The air conditioning unit extracts 65% by weight of room air. The balance being made up by outside at 34.7°C DB and 60% RH. Determine the following: a. mass flow rate of supply air in kg/s b. sensible heat load in kW at the conditioned room c. latent heat load in kW at the conditioned room d. total heat load in kW at the conditioned room e. refrigeration load in kW

Question

An air conditioning unit delivers 8.24 m3/s of air

at 15.2°C DB and 85% RH to maintain 26.5°C DB

and 50% RH room conditioned. The air

conditioning unit extracts 65% by weight of room

air. The balance being made up by outside at

34.7°C DB and 60% RH. Determine the following:

a. mass flow rate of supply air in kg/s

b. sensible heat load in kW at the conditioned

room

c. latent heat load in kW at the conditioned room

d. total heat load in kW at the conditioned room

e. refrigeration load in kW
