Sample procedures are shown below: Example : (IP System) Select an Air Cooled Package Chiller giving a capacity of 70.0 TR to cool water from 54ºF to 44ºF at 00 ft. altitude, fouling factor, power supply 45V/3Ph/50Hz an 5 ºF ambient Temperature. Find compressor power input in kw. Selection: Apply the following factors to convert the required capacity to tabulated capacity ratings. Capacity Multiplier Power Multiplier Altitude Tabulated rated capacity = = 7.7 TR Refer to capacity rating 50Hz under 5 ºF condenser entering air temperature and select a chiller giving a capacity nearest larger to 7.7 at 44 ºF LCWT. Select model APCY 595-S giving a capacity of 75.3 TR and PI = kw. Apply correction factors to the selected unit to find actual capacity and P I. Capacity = 75.3x 0.99 = 73.5 TR P I = x.0 = kw Calculation of Water Flow Rate (WFR) To calculate the water flow rate to be circulated, use the following: WFR (US gpm) = C.CAP (TR) x 24 Range (ºF) 73.5 x 24 = = 46.4 US gpm 0 Example 2: (SI System) Select an Air Cooled Package Chiller giving a capacity of 630 kw of refrigeration to cool water from 2ºC to 7ºC at 60M altitude, 0.08 fouling factor, power supply 380V/3Ph/60Hz and ºC ambient Temperature. Find compressor power input in kw. Selection: Apply the following factors to convert the required capacity to tabulated capacity ratings. Capacity Multiplier Power Multiplier Altitude Tabulated rated capacity = = kw Refer to capacity rating 60Hz under ºC condenser entering air temperature and select a chiller giving a capacity nearest larger to at 7 ºC LCWT. Select model 60-S giving a capacity of kw and PI = kw. Apply correction factors to the selected unit to find actual capacity and P I. Capacity = x 0.99 = kw P I = x.0 = kw Calculation of Water Flow Rate (WFR) To calculate the water flow rate to be circulated, use the following: WFR (L/s) = C.CAP (kw) x Range (ºC) x = = 3.4 L/s. 5 For more details refer to other specifications and dimensional drawings for the selected model. 29

55 APCY Series - R-34a Location And Space Requirements To enhance system performance and operating economy, certain precautions should be followed before installation. SINGLE UNIT INSTALLATION. There should be no obstruction on the air discharge. 82" (83) COIL SIDE 2. Unit must not be installed in a pit or near a parapet wall that is taller than the unit height. 3. Orient the unit so that prevailing winds blow parallel to unit length. If it is not practical to orient in this manner, a wind deflecting shield should be considered. END END 4. Provide adequate clearance on all sides of the unit for service access and avoid coil starvation. Refer to figure below for recommended clearances. Recommended Clearances It is a necessity that the units are installed with adequate free space around them to ensure proper circulation of air that is rejected by the condensers and to provide adequate space for unit access for servicing and maintenance. There is a possibility of recycling of air if the rejected air from condenser encounters any obstacles leading to an increase in the ambient air temperature surrounding the units. Air distribution across the entire heat exchange area will be impaired if the air outlet is obstructed. These conditions lead to a reduction in the heat exchange capacity of the coils causing an increase in discharge pressure of the compressors. This leads to a loss of capacity & increase in compressor power input. Units should not be completely shrouded with higher uninterupted wind shield in order to prevent reversing of airflow. In case, such a configuration cannot be avoided, a properly designed exhaust duct or hood that does not influence any additional pressure on the fans and which is of the same height as surrounding shield to be installed. For installation involving more than 3 chillers, consult SKM for acceptable clearance. 82" MULTIPLE UNIT INSTALLATION (83) 60" (524) COIL SIDE 60" (524) HEIGHT HEIGHT SHOULD BE LESS THAN UNIT HEIGHT MULTIPLE UNIT INSTALLATION 22" (3099) 82" (83) Foundation 60" (524) Figure A 60" (524) Provide a level and rigid concrete foundation or a steel platform that is strong enough to carry the operating weight of the unit. SKM Air Conditioning is not liable for any damages and problems in the equipment caused by erroneous design in the foundation. 55

56 APCY Series - R-34a Water Piping Practices SKM suggests abiding by the local authorities chilled water piping recommendations and practices as they can provide the installer the building and safety codes required for the installation. Water piping should be designed to have a minimum number of bends and horizontal piping levels. Below are the following components it should have:. Temperature and pressure gauges in entering and leaving chiller water piping for unit servicing and commissioning. Pressure gauges must be installed on the same level. 2. Vibration eliminators in entering and leaving chilled water piping to lessen the sound and vibration transmitted to the building. 3. Pipe strainer in the evaporator entering piping to protect the evaporator from water debris and maintain chiller efficiency. 4. Water flow switch in the leaving chilled water piping, wired to the terminals provided in the control panel, to make sure that it has sufficient flow of water in the evaporator. This will prevent the evaporator from freezing up when the water flow is interrupted and avoid compressor slugging on start-up. 5. To isolate the unit from the piping system when servicing or during maintenance, install a shut off valve on the entering and leaving chilled water piping. 6. Expansion Tank provides additional space in the chilled water piping system as temperature rises and furthermore, it maintains a positive pressure within the working limitations of the system. 7. Air Vents at high points in the chilled water system to bleed air from the system. 8. Vapor barrier on the outside of the insulation to avoid condensation in the cold surface of the pipe that may cause damage on the building structure. A thorough leak test should be made before insulating the pipe. Flush all chilled water piping before making the final connection to the unit. SKM recommends hiring services of water treatment specialist to determine the type of necessary treatment. Improper or untreated chilled water leads to scaling, erosion, corrosion or algae that can cause inefficient operation and tube damage. SKM will not be liable for damages caused by improper or untreated chilled water. Run the pumps 2 to 3 minutes before starting the chiller to ensure no freezing occurs that may damage the evaporator.

57 APCY Series - R-34a Vibration Isolation It is recommended to install under the base of the unit a vibration isolation of rubber-in-shear or spring type for further reduction of sound and vibration transmission to building structures. Vibration isolators must be correctly designed for each mounting loads of the unit. Refer to unit certified drawing for operating weight at each mounting points. Leveling Bolt Upper Housing Lower Housing Lower Housing Spring Cap Anti Frictioner Coil Spring Non skid pad Non skid pad Detail-A Detail-A A A Note : SKM can supply CAVM Spring type Anti-vibration mounts (optional). The CAVM has a deflection of 25mm and each rated load can be distinguished easily as it is represented by different colours. Water Loop Volume In chilled water system, presence of sufficient volume of water in the piping system is crucial to achieve proper operation, unfortunately, some systems will run with less water volume than needed, this will result in inconsistence system operation, and uncontrolled compressor cycling, this condition is called short water loop. If our building for example didn t provide enough water volume to achieve stable controls, a storage tank should be installed to increase the water volume. In a standard air conditioning application, the tank should be sized to attain at least 2 minute water loop and minute water loop for process cooling systems. Having enough water loop time, hence enough water volume in the evaporator loop will prevent irregular compressor cycling, which means smoother operation. 57

58 APCY Series - R-34a Evaporator Water Flow Rate and Temperature Range APCY Series can operate at wide evaporator temperature range, 8ºF (4.4ºC) - 6ºF (8.9ºC), within the water flow rate limits, and is flexible enough to permit leaving water temperatures ranging from 4ºF (5ºC) - 48ºF (8.9ºC). The minimum and maximum water flow rates of each evaporator are shown in the Evaporator Water Pressure Drop table. Although in a lot of process cooling applications, it could be found that the flow rates or leaving temperatures are outside the specified limits, however this can be solve by making changes in the chilled water piping arrangement. 58

59 APCY Series - R-34a Unit Sizing Multiple Chiller Operation It is strongly recommended to size the chiller for the present load. For future expansion, it is recommended to install another chiller to meet the additional load demand. If the capacity requires installing more than one chiller unit or where standby units are desired, units should be of equal size (or near) to ensure balanced water flow. Over sizing of chillers by more than 0% at design conditions must be avoided. Over sizing causes energy inefficiency (more power consumption), erratic system operation and shortened compressor life due to excessive cycling of compressors. SKM recommends that water flow supply & return are connected either parallel in case of range < 6 F (8.9 C) or in series if range > 6 F (8.9 C).
