The heat capacity rate is found by multiplying the mass flow rate and the specific heat of water. (1) Once the liquid enters the heat exchanger it transfers heat into the air. The amount of heat transfer, at steady state, is equal to the heat produced by the component. Figure 1. Closed Loop Liquid Cooling System .
The building heating/cooling load calculations, used in the load phase of the program for annual energy consumption analysis, are of sufficient detail to permit the evaluation of the effect of building data such as orientation, size, shape and mass, heat transfer characteristics of air and moisture, as well as hourly climatic data.
This approach allows cooling load to be calculated manually by use of simple multiplication factors. CLTD is a theoretical temperature difference that accounts for the combined effects of inside and outside air temp difference, daily temp range, solar radiation and heat storage in the construction assembly/building mass.
This means the average temperature is 9*c so we lookup the water properties at this temperature to find the density of 999.78kg/m3 and a specific heat capacity of 4.19kJ/kg/K. Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. Q = (999.78kg/m3 x 0.0995m3/s) x 4.19kJ/kg/K x ( (12*c+273.15K) – (6*c+273.15K))
Latent and sensible cooling and heating equations - imperial units. The sensible heat in a heating or cooling process of air (heating or cooling capacity) can be calculated in SI-units as hs = cp ρ q dt (1) where hs = sensible heat (kW) cp = specific heat of air (1.006 kJ/kg oC) ρ = density of air (1.202 kg/m3 ) q = air volume flow (m3 /s)
