PRESERVING THE ENVIRONMENT The discovery of hole in the earth's ozone layer over Antarctica in 19 led the movement to reduce the use of CFC's or chlorofluorocarbons. CFC's are having high ozone depleting potential. HCFC's are also containing some ozone depleting potential and are scheduled to be banned on Being responsible in preserving the environment, you have the right choice of choosing ROYAL TEMP's Air Cooled Condensing Unit Series HX employing R-134A as refrigerant because R-134A is an HFC (chlorine-free) refrigerant with a low ozone depleting potential and direct global warming potential. R-134A refrigerant is not affected by the Montreal Protocol on substance that depletes ozone layer. 2

3 Easy to Access Components More Efficient Air Cooled Condensers Easy to Install and Maintain Preserving the Environment GENERAL Royal Temp HX Series Air Cooled Condensing Units are factory fabricated and assembled comprising of compressors, condenser fans and motors, high efficiency condenser coils, and electrical control box. UNIT CONSTRUCTION These types of RCD Air Cooled Condensing Units are simple, with small footprint, easy to install and maintain due to ease of components accessibility. It features side intake and vertical top discharge. A weatherproof electrical cabinet is provided to protect the electrical components. The unit base provides sturdy foundation and simplified installation. COMPRESSOR Units are provided with hermetic scroll compressors or semi-hermetic reciprocating compressors. The compressor motor is equipped with thermal overload protection. FAN AND MOTOR Fans are propeller type and made up of aluminum blades rigidly fastened to steel hub. The multi-blade fans are individually driven and directly coupled to motor. The fans are statically and dynamically balanced and are protected by epoxy coated fan guard. The motors are equipped with inherent thermal overload protection and permanently lubricated bearings. Motors are air over type. CONTROL Pre-wired controls include operational and safety control devices such as contactors, high and low pressure switches. REFRIGERANT CIRCUIT Each refrigerant circuit's liquid and suction lines are provided with isolation valve thereby allowing the refrigerant charge to be stored in the condensing unit and allowing the interconnecting pipes to be isolated. COIL Condenser coils are constructed with enhanced copper tubes mechanically bonded to aluminum fins having self spacing collar. The coil assembly frame is made up of galvanized steel sheet. Sub-cooling circuits are provided integral to condenser coil to provide refrigerant effect and eliminate flash gas affecting the capacity of the unit. The brazed joints and the possibility of refrigerant loss are reduced due to mechanically U-formed tubes compared to a plate finned coil with brazed return bends. The coil assembly is pressure tested to 400psig while submerged to warm water. 3

5 RATINGS AND SELECTION Royal Temp RCD Air Cooled Condensing Units may be used with air handling units, direct expansion coils in built up systems, remote mounted water chillers with numerous other evaporator units. Capacity ratings as shown in tables and charts are for R-134a refrigerant. Ratings shown are at saturated suction temperatures at the compressor. In actual practice, suction line pressure drop reduces the compressor capacity and compressor must operate at a lower suction pressure to maintain the desired evaporator temperature. It is usually standard practice to size the suction line for a maximum pressure drop of 3 PSIG which corresponds to 2 F. Therefore, the evaporator will operate at an approximately 2 F above the compressor suction temperature and this should be taken into consideration when selecting evaporator. SELECTION PROCEDURE The following conditions are needed to select Royal Temp RCD Air Cooled Condensing Units. Total cooling load (BTUH) Air temperature entering condenser ( F) Evaporator temperature ( F) SAMPLE SELECTION #1 (Condensing Unit matched with Royal Temp ATX Air Handling Unit) Given: Total cooling load: 410,796 BTUH = 411 MBH Air temp. entering cond.: F Evaporator temp.: 40 F to 50 F Suction line loss: 2 F Find: Air Cooled Condensing Unit Model Suction temperature at compressor and evaporator temperature at which the condensing unit and evaporating unit will balance with suction line loss considered. Solution: Referring to Performance Table it is found that model 35HX has the capacity to meet cooling load requirement. Provided that at arbitrary evaporator refrigerant temperatures of 40 F and 50 F the capacities are MBH and MBH respectively. Plot the above total capacities on the 35HX condensing unit capacity chart as shown in the figure. Draw a straight line from A to B establishing the evaporator coil capacity line. Take suction line loss into consideration, move horizontally left 2 F from points A and B and establish points C and D. Draw a straight line from point C to point D establishing system capacity line. Capacity, MBH From the system capacity line CD determine the balanced conditions as follows: At the intersection of the system capacity line and the F ambient air draw a line horizontally to the left and read capacity as MBH. From same intersection point draw line vertically down to suction temperature line and read the suction temperature at compressor as 40.4 F. From same intersection point draw line horizontally to the right to evaporator capacity line AB and establish an intersection point. From this intersection point draw line vertically down to suction temperature line and read the evaporator temperature as 42.4 F HX C A 40.4 Ambient temperature, F Suction Temperature, F Using Performance Table and interpolating between 40 F and 45 F suction temperatures, the KW input at 40.4 F is kw. SAMPLE SELECTION #2 (Typical Evaporator) Given: Total cooling load: 214,000 BTUH = 214 MBH Air temp. entering cond.: F Evaporator temp.: 47 F Suction line loss: 2 F Find: Air Cooled Condensing Unit Model Suction temperature at compressor Solution: Examination of the condensing unit capacity data contained in the table quickly determines that a model 18HX appears to have the capacity to meet the requirements. Referring to Performance Table, it can be determined that 18HX will produce the required capacity of MBH at compressor suction temperature of 45 F (taking into consideration 2 F suction line loss) and F air temperature entering condenser.
