0. Summaries of product characteristics

0-1. Product explanation

(1) Excellent for peak shaving during high electrical demand periods.

(2) esigned to provide chilled water from waste heat sources, generated from industrial

processes and cogeneration systems.

(3) Allows diversification of critical cooling requirements. Critical cooling loads are met

with minimal electrical power input with a hot water-fired chiller.

(4) Allows for smaller generator set installation be utilized since the electrical load

associated with an absorption chiller is minimal when compared to an electric chiller.

(5) Ozone safe, CFC free. Cooling requirements are met without chlorine based

refrigerants.

(6) Reduces affectors to global warming. Minimizes global impact by greatly reducing

electricity consumption and eliminating the use of greenhouse gases.

(7) Environment: Molybdate solution inhibitor is used with no impact on environment.

(8) Low noise and vibration. The absorption chiller doses not utilize a large

motor-compressor, and this leads to quiet, trouble-free operation.

(9) Small footprint saves facility space.

0-2. Use of product

Absorption Chiller is air conditioning equipment achieving comfortable space, energy

saving, and economic efficiency.

It has been used in office buildings, hotels, department stores, hospitals, schools,

convention centers, government building, etc.

① Keep the purge va ve shut tight y to prevent air from eaking into the Chi er, which may

cause the fai ure of the Chi er.

② Keep to turn on the power supp y to the contro pane without maintenance service.

③ During the di ution cyc e operation of the Chi er as we , the chi ed water pump (both the

primary side and the secondary side) and air hand ing unit must be operated for the necessary

time. The Chi er has a itt e coo ing capacity even if it is in the di ution cyc e operation.

Do not stop the air hand ing unit before the necessary time to prevent possib e subcoo ing.
