LCA
The compressors often work intermittently, since the chilling requirements of the user generally do not
coincide with the compressor output. In systems containing little water, where the thermal inertia of the
water itself is lower, it is a good idea to check that the water content in the section delivering to users
satisfies the condition below:
V = water content in user section
Sh = specific heat of the fluid
ρ = fluid density
Dτ = minimum time lapse between 2 compressor restarts [s]
DT = allowed water T differential
Cc = Cooling capacity
Ns = N° of choking steps
