1.3 PERFORMANCE REQUIREMENTS<br />

A. Each chiller shall produce a capacity as scheduled on plans when operating on a fluid<br />

mixture of 30% propylene glycol.<br />

B. The coolers shall be selected for 0.00010 fouling factor. Water side shall be designed for<br />

150 psig working pressure. The condenser shall be selected for 0.00025 fouling factor.<br />

Water side shall be designed for 150 psig working pressure.<br />

C. Chillers shall give 15 to 25% more capacity with better efficiency when condenser water<br />

temperature is lowered.<br />

D. Seismic Performance: Centrifugal chillers shall withst<strong>and</strong> the effects of earthquake<br />

motions determined according to California Building Code.<br />

1. The term "withst<strong>and</strong>" means "the unit will remain in place without separation of<br />

any parts from the device when subjected to the seismic forces specified."<br />

E. Condenser-Fluid Temperature Performance:<br />

1. Startup Condenser-Fluid Temperature: Chiller shall be capable of starting with<br />

an entering condenser-fluid temperature of 40 deg F <strong>and</strong> providing stable<br />

operation until the system temperature is elevated to the minimum operating<br />

entering condenser-fluid temperature.<br />

2. Minimum Operating Condenser-Fluid Temperature: Chiller shall be capable of<br />

continuous operation over the entire capacity range indicated with an entering<br />

condenser-fluid temperature of 55 deg F.<br />

3. Make factory modifications to st<strong>and</strong>ard chiller design if necessary to comply<br />

with performance indicated.<br />

4. Site Altitude: Chiller shall be suitable for altitude at which installed without<br />

affecting performance indicated. Make adjustments to affected chiller<br />

components to account for site altitude.<br />

5. Performance Tolerance: Comply with the following in lieu of ARI 550/590:<br />

a. Allowable Capacity Tolerance: Zero percent.<br />

b. Allowable IPLV/NPLV Performance Tolerance: Zero percent.<br />
