Extended Functions：

ERACS.E-Q1 R134A refrigerant series
ERACS.E-Q1-Z5 R513A refrigerant series

Frame Structure Description：

Base and frame in thick hot-galvanised shaped sheet steel. All parts polyesters-painted.

Compressor Description：

● Semi-hermetic screw compressor specially designed for HFC134a with higher compression efficiency under full load as well as part load;
● Precisely manufactured twin-screw rotor with aircraft-grade bear featuring in high reliability, low noise, low vibration and stable running;
● The motor drive the bear directly with least moving component and wearing part that cause no energy loss and higher mechanical efficiency;
● Automatically adjust power output according to load by microprocessor. The slide valve is fixed for stepless control and increase part load performance.

Evaporator Description：

●Direct expansion heat exchanger type with asymmetric refrigerant paths to maintain the correct refrigerant velocity inside the tubes during both liquid and gaseous phases.
●The steel shell is insulated with a closed-cell anticondensation lining. The copper pipes are internally grooved so as to improve the heat exchange. The pipes are mechanically expanded onto the tube plate ends. An antifreeze electric heater prevents the formation of ice inside the casing of the exchanger when the unit is not operating but connected to the electrical supply. Differential pressure switch for controlling the water flow is fitted standard.
●The design, manufacture and inspection of the evaporator comply with national standards and regulations for pressure vessels such as GB / 1515019771 steel pressure vessels and JB / 4765 pressure vessels for refrigeration devices.

 

Condenser：

●The inverted M-shaped structure is adopted to increase the heat exchange area on the premise of constant unit volume; Uniform wind speed distribution, high-performance heat exchange, reduced frosting time during heating, and improved heating and defrosting performance;
● With corrugated sheet design, the condenser of the unit is not easy to be blocked, the maintenance cost of the unit is reduced and the service life is longer; The aluminum sheet adopts thickened design, which is not easy to collapse;

Control Cabinet：

●The unit startup and microcomputer control parts are integrated into the same control cabinet and located at the front of the unit, which is convenient for the on-site operators to operate in the machine room and between the units. The maintenance of all electrical parts can be carried out at the front of the unit.
● The electrical control box is made of high-quality steel plate, and the external surface has been galvanized and anti-corrosion treatment, which can effectively protect the electrical components of the unit.
● For the safety of the operator, once the host is powered on, the operator will not be able to open the isolation board between the control and electrical components to ensure the safety of the operator.

Control System：

● New generation regulation system with human-computer interface, better extended utility, supervision and compatibility.
● Panel screen on the unit, easy operation, better protection Microprocessor regulation fulfill human-free running.
● W3150197711501977115019771 with LCD display, multi-language & multilevel menu for data display & set-point regulation .According to CLIMAVENETA tradition, another display of compressor’ working data is adopted for easy supervision.
● Dedicated W3150197711501977115019771 microprocessor is inserted with CLIMAVENETA control algorithm to make sure energy saving and reliability.
● FIFO compressor running time balance function extends unit’ working life;
● Auto compressor power input control following with load change from 25-11501977115019771% for energy saving;
● Environment adaptation by data regulation and setting;
● Modulating measurement is used for temperature pressure protection. It can increase reliability and predict fault occurs.
● Expansion kit for remote control and group control.
● Available in BMS control, such as ModBus, LonWorks, BacNet control system.
● Microprocessor have complete fault predict, alarm, record and self diagnose function assuring operation protection & working state.
● “Black Box” record 41501977115019771 faults and 21501977115019771 data before each fault, which diagnose & remove fault quickly
● We also can find potential fault and take preventive action before it occur by CLIMAVENETA remote service program

         

Certification and Honor：

Electric Control：

Electric Expansion Valve：

EEV for precise control to meet load change.

 

High Performance Fan：

High efficiency exterior rotor fan from German brand with variable speed controller. It can change fan speed automatically (DVV design) to reduce energy consumption and fan noise.

Innovative Intelligent Defrost Function (CLIMAVENETA Patent)：

The reverse cycle type intelligent defrost function introduce the self-adjust technology which can automatically modify and regulate the judgement and data for next defrosting according to the change of ambient air temperature, humidity and defrost time as well as the difficult level of last defrosting. So the defrost no longer need manual adjusting and it can be fit for all kinds of weather condition.Much precise, reliable and energy saving from traditional defrosting method.

Automatically balance：

In the 4-pipe air-cooled screw unit, each refrigeration circuit has three heat exchangers: cold water heat exchanger, hot water heat exchanger, and balance heat exchanger. The cold water heat exchanger produces cold water all year round, the hot water heat exchanger produces hot water all year round, and the balance heat exchanger can be used as both a condenser and an evaporator. When the loads of the cold and hot water heat exchangers cannot be balanced with each other, the balance The heat exchanger is automatically put into work immediately for cold and heat compensation, matching any demand for cold and hot water loads in real time, and the output of cold and heat is more arbitrary.

Environmentally friendly refrigerant：

● Environment friendly HFC134a;
● Optimize the refrigerant system to reduce energy consumption and CO2 emission;
● Optional low GWP, environmentally friendly refrigerant R513A
