Component Selection and Balancing

10.1 INTRODUCTION

This chapter will deal with some fundamental approaches in order to provide an understanding of the processes and issues involved with selecting and balancing hardware. For many systems specifications will predetermine some of the con­ditions and constrain the options. For example, a supermarket chain may spe­cify the evaporating, condensing temperature and refrigerant to be used. These constraints simplify the task and make comparisons easier. Moreover excellent selection software available from manufacturers and other sources can provide component and package equipment data for any desired operating conditions.

The information is based on refrigeration applications, but the same prin­ciples apply to air conditioning. Certain parameters such as air humidity can play a more dominant role in air conditioning.
