When I take the proposed model, save as, and then just change the system type to the DX CV system, the cooling loads in the SS-D report <i>change.</i> They are less when the DX CV system. How can the <i>loads</i> change? These should stay the same and the energy used to meet these loads should change. Has anyone run into this before? <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-family:"Century Gothic","sans-serif"'>Kristy M.
