absorption system?
By entering your details above, you agree that CIBSE may contact you from time to time with
A The lower the ambient temperature for heat rejection, the
information about CPD and other training or professional development programmes, and
greater the COP
about membership of CIBSE if you are not currently a member.
B The lower the refrigerant evaporating temperature the
greater the COP
