7 SCROLL COMPRESSOR The scroll compressors are consists of two involutes or Archimedean spirals (Figure-G). One spiral is positioned inside the other to form a series of crescent-shaped pockets. During compression the upper spiral remains stationary and the lower one, being eccentrically mounted on the drive shaft, describes an orbital rather than a simple rotary motion. () () (3) (4) (5) FIGURE- E (Compressor working principle) FIGURE- F (Scroll compressor). Compression in the scroll is created by the interaction of an orbiting spiral and a stationary spiral. A refrigerant enters the outer openings as one of the spirals orbits.. The open passages are sealed off as gas is drawn into the spiral. 3. As the spiral continues to orbit, the gas is compressed into two increasingly smaller pockets. 4. By the time the gas arrives at the center port, discharge pressure has been reached. 5. During operation, all six gas passages are in various stages of compression at all times, resulting in nearly continuous suction and discharge. Refrigerant enters the compressor at the suction connection and flows around the motor s housing and enters at the bottom side through the openings and oil droplets separate from the refrigerant and fall into the oil sump. All suction refrigerant passes through the electrical motor, ensuring full motor cooling, after that the refrigerant enters the scroll elements.

FAN CYCLE SWIH HEAD PRESSURE CONTROL (FCS) The capacity of air-cooled condensers varies with the difference between condensing temperature and condenser entering air temperature (ambient temperature). It increases as this difference increases. For a given capacity, a drop in the ambient temperature will lower the condensing temperatures and if the ambient temperature drops below a given limit, head pressure control is required. Control shall be set for a minimum of 95 F (35 C) saturated refrigerant condensing temperature, or to suit the specified application. M. ADJUSTABLE HIGH PRESSURE SWIH (HPS) A field adjustable high pressure switch provides safety protection in the case of excessive discharge pressure. Typical factory pressure settings are shown in the table below: OPEN CLOSE 350 ± 0 Psig 300 ± 0 Psig N. ADJUSTABLE LOW PRESSURE SWIH (LPS) a field adjustable low pressure switch provides safety protection in the case of low suction pressure and loss of refrigerant charge. Typical factory pressure settings are shown in the table below: OPEN CLOSE 5 ± 5 Psig 50 ± 5 Psig O. COMPRESSOR CIRCUIT BREAKER This feature protects against compressor branch circuit fault. When tripped (manually or automatically), the breaker cutoff the power supply to the compressor and disable its control through the breaker's auxiliary contacts. P. ECONOMIZER/CO MONITORING The economizer permits low cost operation by utilizing cool outdoor air for free cooling. A damper on the economizer controls the amount of outdoor air and on closed position it provides a leak proof seal. It can easily be adjusted for 00% outdoor air, 00% return air or any proportions of mixed air. The economizer is operated either by a dry bulb outdoor air thermostat (OAT) or a solid state enthalpy controller (EC) used to sense the outdoor air temperature. The unit is equipped with an electronic control board and the economizer uses controller with a sensitive feedback system that carefully modulates the damper to allow correct percentage of fresh air and return air. The economizer controller is designed to match with the Zamil electronic thermostat.. OUTDOOR AIR THERMOSTAT (OAT) ECONOMIZER CONTROL Economizer operation is governed by outdoor temperature and unit OAT setting, as follows: a. Outdoor Temperature > Outdoor Air Thermostat (OAT) setting: If the thermostat calls for cooling, the economizer damper moves to minimum position, simultaneously blower motor, compressor- & fan motors would start. If further cooling is required, compressor- also starts with a time delay. After the thermostat is satisfied the compressors are staged out. The economizer controller moves the damper automatically to closed position simultaneously the blower is also shutdown. b. Outdoor Temperature < Outdoor Air Thermostat (OAT) setting: As the cooling load would be low, the economizer controller will operate as stage- of cooling system first switching ON the blower motor simultaneously modulating the damper in steps to required position, allowing the cool outside air into indoor side. If further cooling is required compressor- & fan motors will switch ON as stage- of the system, whereas compressor- is pulled out of service. As the room temperature is attained, economizer controls will cut-off the compressor, fan motors simultaneously closing damper to fully closed position. 4

17 . ENTHALPY SENSOR FOR ECONOMIZER CONTROL The solid state enthalpy sensor is capable of accurately sensing outdoor air enthalpy content (temperature & humidity) and controlling the economizer damper for the minimum heat content introduce to the evaporator coil. Thereby, providing an efficient & economical system operation. 3. CO MONITOR Indoor air quality (IAQ) is becoming more and more important, CO monitoring give an indication of the amount of CO inside a facility. Once it is exceeding a certain level it sends a signal to the control system demanding for fresh air to replace the inside poor quality air. The control is responding in opening the damper and at the same time there is input in the control for an exhaust relief fan externally connected to the unit as it purge the poor quality air. Economizer System Schematic with CO Monitor Q. ULTRA VIOLET LIGHT FOR IMPROVED INDOOR AIR QUALITY. Improved Overall Indoor Air Quality When used for general IAQ control, UV FLOW TM products can successfully: Control fungi in HVAC systems to reduce or eliminate mold-related allergies. Prevent the development of different types of bacteria. Reduce the spread of cold and flu viruses and other airborne-transmitted diseases. Eliminate odors and maintain a fresh air smell indoors. UV FLOW TM Emitters pose no risk to components, equipment or inhabitants. Their non-chemical energy kills organisms without producing secondary contamination and costs little to operate.. Save Energy and Cut Costs UV FLOW TM can reduce maintenance cost as UVC lights successfully eliminate the bio-film (dirt) that fouls surface of heat exchangers - completely cleaning and continuously maintaining coils and drain pans to 'as new' conditions. This in turn improves heat-transfer efficiency, coil pressure drop, and fan performance. R.

18 S. ELECTRONIC THERMOSTAT General information: Electronic thermostat shall control one or two stage heating and cooling applications. The thermostat normally displays room temperature and mode of operation. The temperature can be set by up/down buttons for both cooling and heating cycles. The thermostat also allows you to select continuous fan operation, or have the fan on intermittent operation with the equipment. The thermostat is best located about 500 mm (5 Ft.) above floor level, on a partition wall (not an outside wall), and should not be exposed to direct light from lamps, sun etc. It should be in return air stream, away from supply air registers/diffusers. Single/dual stage - Cooling & heating. Low voltage control - 4 VAC (nominal). Room temperature display - in 0 C or 0 F. Mode of operation - FAN/COOL/HEAT/AUTO. Fan mode - ON: Continuous fan operation; AUTO: Fan operates ON/OFF with compressor. Heating & cooling setpoint is permissible. Temperature set button - Up for increasing & down for decreasing temperature. Remote sensing function as an option. T.

Power supply (V-Ph-Hz) : Unit type : Front fan supply (front return air). Unit selection based on required cooling capacity Enter cooling capacity performance data at condenser entering air temp. at 5 0 F and evaporator entering air temp F DB, 67 0 F WB, 400 CFM airflow. The PAX040 unit will give 43,840 BTUH cooling capacity (gross) and 39,000 BTUH sensible heat capacity (gross). 3. Electric heater selection Heating capacity required = 40. Enter electric heating table for PAX040 at power supply. 40 heater at 460 volts satisfies the required heating. 4. Determine fan speed and power requirements at design conditions Before entering the fan performance tables, calculate the summation of external static pressure for the required components as follows. External static pressure Additional module :.6 INCH WG. : NIL.6 INCH WG. Enter fan performance table for PAX040 model. For 4000 CFM and external static pressure of.6 INCH WG, it require 73 RPM and 9.06 fan power consumption () wherein the standard motor will meet job requirements. 5. Determine input power to motor Use fan motor efficiency table Blower motor watts = = = 9,956 Watts. Motor efficiency Determine net capacities Above capacities are gross and do not include blower motor heat gain. Determine net capacities as follows: Net cooling capacity = Gross cooling capacity blower motor heat = 43,840 (9,956 WATTS x 3.43 BTUH/WATTS) = 397,860 BTUH Net sensible capacity = 39,000 (9,956 WATTS x 3.43 BTUH/WATTS) = 95,00 BTUH 7.To calculate leaving air conditions (see footnote for capacity tables) DBL = DBE (Sensible Capacity (Btuh) /.08 x CFM) WBL = DBL [DR (DBE WBE)] WBL WBE When sensible capacity approaches.0, especially at entering DB higher than 80 0 F, find DBL in the same manner above, but WBL is to be found from intersection of DBL Line on a psychrometric chart with the horizontal line of humidity ratio (W) where (at SHR = ), WL = WE.

91 CONTROLS & SEQUENCE OF OPERATION Scroll compressors are designed to operate in single direction only. Hence, care has to be taken to ensure correct rotation when the system is operated. Verification of correct rotation is by observing that the suction pressure drops and discharge pressure rises when compressor run. Reverse rotation results in abnormal sound, as well as, substantially low current draw and by interchanging power supply wire L & L3 will correct this problem. The operation of the air conditioning unit is controlled by a 4VAC electronic control board. GENERAL The thermostat normally displays room temperature and mode of operation. The five buttons on the front of the unit allow complete control of the thermostat. The thermostat also allows to select continuous fan operation (useful when using an air cleaner) or have the fan come on with the compressor. SWIH FUNCTION - On/Off Key : Switch the system On or Off. - Up Key : To increases the set temperature. - Down Key : To decreases the set temperature. - Mode Key : Changes the mode to Fan, Cool, Heat or Auto. - Fan Key : Changes the Fan Operation to Auto or Continuous. - C/ F selection : By pressing Mode & UP key together, toggles between C to F or vice versa. USER CONTROLS Mode: Select the desired mode of operation by pressing of the mode button: FAN COOL HEAT AUTO Fan: In this mode of operation, the compressor will be in inactive state. Display shows room temperature. Fan will be running. Cool: In this mode of operation, the compressor will be ON after a delay depending on the differential of room temperature & Set temperature. Heat: In this mode of operation, Fan is ON. Auto: In auto mode, thermostat provide automatic changeover from heating to cooling mode & vice versa. Thermostat automatically switches to maintain the desired temperature. DIP SWIH OPTIONS AND FUNCTIONS There are 4 small DIP (Dual in line package) switches on the back of the circuit board which must be configured by the installer.
