■ DAIKIN adopts the latest R134a efficient single-screw compressor to greatly improve the efficiency.
■ New design of four-way valve lowers the pressure drop. Over-compress technology significantly improves the four-way valve reliability. This design avoids short circuit. In this way, units’ efficiency and stability is much better.
■ The new economizer design increases the unit sub-cooling, greatly promotes the unit’s cooling capacity and EER. Unit full load EER is up to 3.2, and higher EER under part load.
■ New high efficiency counter-flow shell & tube dry-expansion single pass evaporator (one or two internal independent refrigerant circuits)
■ The most advanced efficient single-screw compressor is adopted. The compressor can perform stepless adjustment within the range of 10% to 100% workload at maximum. Compared with the traditional compressors, this compressor has wider adjustment range and higher efficiency.
■ The temperature of outlet water is stable. The output ability meets the workload demand of the construction system. The units can regulate the output based on the actual workload and maintains high efficiency when running at partial workload. In addition, the accurate adjustment of the energy and water temperature brings more comfortable experience to customers.

■ No Chlorine No ODP Good Efficiency
■ New very high efficiency (full and part load) DAIKIN Single Screw compressor. (technology by DAIKIN)
Through meshing between metal and nonmetal, it eliminates the high frequency noise. And with fewer moving parts and rotor load balance, it decreases most vibrations. With a shock absorber, noise and vibrations are lowered further.
■ Integrated design and compact structure are adopted for the units. The base can balance the entire unit weight. The spring-damper on the units helps to eliminate the operation sound and vibration.
■ New high efficiency condenser fans (technology by DAIKIN)
Condenser using high efficiency, low noise resin spiral fan motor, direct drive, 3dB(A) noise lower compared with spiral blades.
■ Flexible installation without additional equipment room, cooling tower, or cooling pump.
■ The electric system of the units is integrated with the master unit, so an additional electric control cabinet is not required.
■ An intelligent control system monitors and controls the operating status of the units and indicates the fault cause for the convenience of maintenance.
■ An advanced electrical expansion valve enables the units to control the refrigerant flow accurately, adapt to various working conditions, and perform multiple control functions.

DAIKIN leads the single-screw compressor technology. The Semi-hermetic compressor features high efficiency, energy saving, quiet operation, few moving components, and long service life.
■ Few moving componentsDAIKIN single-screw compressor consists of only five moving components: a screw rotor, two star wheels, and two energy adjustment slide valves. The screw rotor is a six-tooth aluminum coated steel component. The star wheel is an eleven-tooth component made of high-strength composite material.
■ Long duration and high reliabilityThe star wheels made of high-strength composite material can ensure the accuracy and the minimum gap and guarantee operation without wear and tear. The oil injection and liquid injection design of the compressor minimizes air superheat and eliminates the possibility of oil and refrigerant decomposition due to superheat.
■ Simple maintenanceThe removable side cover of the star wheel box simplifies the routine inspection without the need of removing and installing pipelines. Such a design facilitates the check of the internal components of the compressor.
■ Anticorrosion aluminum fins■ Ammeter and voltmeter■ High/low pressure gauge■ Soft starter■ External manual operator■ Building automation ports: Modbus, Lon Works, and
BACnet.
DAIKIN ultra-efficiency single-screw compressor (intended for R134a refrigerant)
Features
Options
■ Low operation sound and vibrationDAIKIN single-screw compressor can balance the load completely during its operation. Therefore, the vibration can be ignored because the noise value is lower than the industrial standard. The compressor does not contact with any metal during compression so that no high frequency noise is generated. The special-shaped air discharge cavity helps eliminate noises effectively.
■ Unique star wheel and rotor designThe star wheel of DAIKIN single-screw compressor is made of special materials that can avoid metal engagement between the star wheel and rotor. The small engagement gap and low engagement resistance implement “zero gap" engagement. The unique oil supply system that uses the oil pressure difference function enables more efficient sealing, lubrication, and cooling of the compressor. In this way, the engagement resistance is further reduced and the efficiency of entire units is improved.
■ High-efficiency oil separatorThe application of high-efficiency oil separator increases the oil separation rate to 99.7%. The “oil leakage" problem during the compression is resolved, and the reliability and efficiency of the compressor is improved.

Notes:
■ * This function is not available for cooling-only and total heat recovery units.
■ For the terminal blocks in figures 2 and 3, M3(401) and M3(402) indicate the output contacts for pump control on the air conditioning side; M3(90) and M3(91) indicate the output contacts for pump control on the heat recovery side.
■ For the terminal blocks in figures 9 and 10, M3(53) and M3(54) indicate the signal contacts for auxiliary electric heating on the air conditioning side; M3(28A) and M3(28E) indicate the signal contacts for auxiliary electric heating on the heat recovery side.
■ Operating signals of the unit come from the operating signals of the water pump. If M3 (401) and M3 (402) are externally connected to a water pump contactor, the operating signals of unit come from the normally-open contact of the contactor.
■ When the unit is in the remote mode control, switch Q8 must be set to “Heating". It can be controlled by connecting a remote switch to M3 (60) and M3 (61). The short contact tag between M3 (60) and M3 (61) must be removed.
■ The failure, water pump output and electric heater contact can bear an AC voltage of only 230 V. If the water pump contactor uses a 380 V coil, conversion is required. See Figure 3/10.
■ Since the units are under constant improvement, use the drawing delivered with the related unit for reference.

On-site wiring diagram
Mandatory components for the water system:
No. Mandatory Components
1 A heat insulation layer with a thickness of at least 10 millimeter must be wrapped around the chilled water pipe.
2 A water filter with at least 25 meshes per square inch must be installed at the inlet of the water-side heat exchanger.
3 The chilled water pipe must be cleaned by using a bypass pipe. It’s prohibited to clean the water pipes through the water-side heat exchanger.
4A water flow switch must be installed at the water outlet of the water-side heat exchanger. The distance of the level straight pipe between both ends of the flow swith must be five times more than the diameter at least.The water flow direction in the
water flow switch must be the same as that in the water system.
5 A relief valve with a opening pressure less than 1.0 MPa must be installed.
6 An automatic water replenishment device must be installed to ensure sufficient water in the water system.
7 A pump with a proper water flow and lift must be installed at the water inlet of the water-side heat exchanger to ensure that the actual water flow is between 70% - 130% of the rated water flow for the unit when the unit is working.
8 Sufficient maintenance space must be reserved.
9 Stop valves must be installed at the water inlet and outlet of the unit.
10 An automatic relief valve must be installed at the top of water pipes to ensure that air in the water system can be discharged when the unit is working.
11An auxiliary heater or other heating devices must be installed to ensure that water in the water system does not freeze when the environment temperature drops below zero (this requirement only applies to areas where the environment temperature
may drop below 0°C).
12 The chilled water pipe must comply with the local piping engineering regulations and rules.
13 The water used in the water system must comply with related industry standards.
Water Flow
Water Volume
The design water flow of water system should be the same as rated water flow of unit. Of course, the unit is able to operate at condition of 70%~130% rated water flow. However, water flow out of this range may cause unit alarm, or even reduce the unit life expectancy.
It is very important to design the water system with suitable water volume. With too much low water volume, air conditioning terminal device will not be able to operate at stable condition, then the user may feel uncomfortable. Moreover, the chiller with lower water volume may be frequently on/off, then may cause the chiller alarm, or even damage evaporator and system.
Minimum water volume: To avoid the above happened, water volume of water system must be at least more than the minimum water volume
Minimum water volume (m3) = Rated cooling capacity of chiller (kW) × 0.0068
DAIKIN Air-Cooled Screw Chiller/Heat Pump

The workload of a DAIKIN water chiller is controlled by the outlet water temperature which can be set by using the unit controller.
By default, the outlet water temperature is set to 7°C. It can be set from 4~15°C. Out of this range, some other parameters are needed to be changed as well. Please contact local DAIKIN office or distributor to have professional technician to do the setting accordingly.
Setting the Outlet Water Temperature
Cleaning the Water System
Requirements on Water Quality
While installing the water system, it may create a lot of welding slag, dirt or other impurity. It may damage the evaporator if the chiller is connected directly to the water system without cleaning. Please do not run the water into chiller until the water is clean and qualified.
Water quality directly affects the performance and life expectancy of the unit. Therefore, the water quality must be tested and properly managed for the unit to work properly.
DAIKIN recommends a water quality that meets the following standards:
Item Standard Item Standard
pH pH:7.5~9 Conductivity <800µS/cm
Total hardness CaCO3: 40~85mg/L Chloride CI-<300mg/L
SO2- SO2-<70mg/L Alkalinity HCO- : 70~300mg/L
NH+ NH+<2mg/L H2S H2S<0.05mg/L
CI2 CI2<1mg/L CO2 CO2<5mg/L
