Preface Preface
Preface
DATA BOOK describes the technical specifications of MITSUBISHI ELECTRIC Corp.'s CITYMULTI air conditioning system
products.
In this DATA BOOK for ground source application, the information on water-cooled heat source unit PQHY-P-T(S)LMU-A1/PQHY-
P-Y(S)LMU-A1/PQHY-P-Z(S)LMU-A1/PQRY-P-T(S)LMU-A1/PQRY-P-Y(S)LMU-A1/PQRY-P-Z(S)LMU-A1 with the connection of
standard CITY MULTI indoor unit series is specified.
For capacity tables with indoor units, refer to the DATA BOOK for standard CITY MULTI units.
We recommend DATA BOOK users to read carefully and take advantage of all the contents inside to design the CITY MULTI air
conditioning system and/or to prepare documents for promotions.
Along with the DATA BOOK, MITSUBISHI ELECTRIC provides a Design-Tool software to ensure the users to design the system
correctly and simplify the calculations.
Please contact your local distributor for this software.
Please be notified that specifications are subject to change without notice due to continual improvements of the product.
For any inquiries, please contact your local distributor.

BRINE INFORMATION BRINE INFORMATION
I.BRINE INFORMATION
Brine freezing temperature
Brine concentration is decided by the freezing temperature. First, it is necessary to decide the freezing temperature and find
out brine concentration which will correspond to the freezing temperature.
The graph was referred from chemical company data.
But Freezing Temperature condition will be slightly different based on each company.
Please confirm detail data to the chemical company directly.
It is recommended to set the brine concentration to a percentage that will keep the freezing temperature at -15°C or less.

BRINE INFORMATION BRINE INFORMATION
Capacity correction by brine concentration (For heat source unit)
Depending on the freezing temperature and brine concentration, the ratio of unit capacity will change.
As shown in the line diagram, higher the brine concentration, the lower the ratio of capacity becomes.
