7.5 CYCLE DESIGN EVAPORATING AND CONDENSING TEMPERATURES
Please make sure that the Heat Exchanger element to be connected to the DX-Interface series 2 satisfies the following installation
and design requirements. Failure to satisfy any of the items below may cause unappropriated system response, malfunction of any
of the system components, and/or damage to the components..
-
The design pressure of the system is 4.15 MPa. The compression strength of the pipes must exceed 12.45 MPa (3 times the
design pressure)
-
The inner volume of the heat exchanger piping must be within the limits specified in the technical documentation of each
DX-Interface series 2. Please make sure the design of the heat exchanger as well as the refrigerant charge follow such
limitations.
-
The capacity of the heat exchanger must meet the specified nominal capacity of each DX-Interface series 2 under the
following temperature conditions. Failure to ensure heat exchanger capacity may lead to system malfunction.
