System Design Guidelines:
The following sections discuss system design guidelines for the EVI product.
Please use Copeland Selection Software (SELECT), where all parameters are given for selecting a single heat
exchanger. The Copeland Selection Software can be downloaded from www.eCopeland.comT.
The key parameter in determining the proper heat exchanger size is the Saturated Injection Temperature (Tsi). The
Tsi has been determined through extensive testing. This value can vary for each compressor and should be obtained
from Copeland Selection Software.
After determining the Tsi, a 5K condenser natural subcooling, 5 K heat exchanger ∆T
and 5 K heat exchanger
HX
superheat are targeted. This is done to optimise system performance while maintaining system reliability and
functionality at the same time. Once these parameters are known, the heat exchanger capacity (kW) can be
determined, which gives the required heat exchanger size. (See Figure 6 below)
