Serdang Hospital (Malaysia)

This Air Conditioning Plant of this Hospital 
incorporates an STL-AC.00-400

Serdang Hospital, which is expected to be operational in 2004, will be the reference center for cardiology, cardiothoracic, urology and nephrology surgery. The hospital will provide affordable, quality treatment for heart patients from the lower income group. The center will cooperate with the Selayang Hospital, which specializes in renal care and liver transplants. The 608-bed Serdang Hospital, which will cost RM300 million or U.S.$79 million, is one of the electronic hospital networks planned by the Malaysian Government to provide better health care services.



Serdang Hospital

 

Objective

To reduce the electrical bill it was decided to install a Thermal Energy Storage Systems (STL). The strategy of use is partial storage.

To assist with project design Cristopia engineers performed simulation studies using Cristopia’s “Stockaid 2000” & simulation software.  The purpose of this simulation was to check the discharge rate capability in the design specifications mentioned below as par ARI Standard 900 ( 4.3°C leaving temperature and  9.5 °C return temperature).  

Using the “Stockaid 2000” simulation software Cristopia technical staff can provide the most appropriate design answers to consulting engineer’s questions.         

Technical Data

Maximum Cooling Demand

:

2,000 Tons

Cooling Energy Stored

:

6,000 Ton hours

STL Storage Volume

:

400 m³

Number of Tank

:

2

Tank Diameter

:

3.4 m

Tank Length

:

21 m

Characteristics

The plant consists of 2 STL tanks of 200 m³, 2 base chillers (400 Tons) and 2 brine chillers (374 Tons).

The STL will supply 23% of the cooling demand and will enable to shift electrical consumption from on- peak to off-peak period. 

Technical Advantages

Smaller chiller capacity
Smaller heat rejection plant
Reduced maintenance
Efficient and reliable system
Energy management
