METHOD OF CALCULATION OF THE ANNUAL CONSUMPTION OF AIR CONDITIONING SYSTEMS COLD

Using the basic principles of simulation the method for calculating of the annual consumption of cold by air-conditioning systems was developed. The initial data are: location of the building and the local weather conditions according to the long-term supervision; estimated barometric pressure; the number of working days, shifts; mass flow rates of the supply air G, outdoor air GH and recirculation Gp; coefficient of recirculation; constant or variable value of the enthalpy of recycling air hp and cooled air hoh; temperature (°C) and the enthalpy of the indoor air. On the basis of the database of the table monthly averages of temperatures tn.m (°C), outdoor air and water vapor partial pressure PH (kPa) the monthly average enthalpy hn.m. using the splines interpolation method, the total share of cold per unit of air conditioning systems air flow, the annual consumption of cold, taking into account the dimensionless factors are determined. The developed method allows to compare the alternative variants of air conditioning systems in the optimization problem.
