Description
Features of chiller of VERTRO JBE:
- Execution type: only cooling;
- Coolant: R407C freon;
- Productivity: from 45 to 188 kW.
KEY FEATURES
Thanks to compact dimensions (width 0,77m, max. height - 1,8m.) the chiller easily passes through a doorway; Thanks to a large number of steps regulations of refrigerating capacity in many cases need of installation disappears tank store; Protection of the evaporator against freezing thanking channel relay; Possibility of work of a chiller on temperature the entering and leaving hladonositel; The special control algorithm guarantees stable work of components of a contour in all operation modes, and also uniform operating time of compressors and pumps; The reduced noise level; Big operational resource. CASE Frame from galvanized steel with powder polyester covering. Rubber vibrosupport. COMPRESSORS Spiral three-phase compressors with heating case and the built-in protection of the engine from overloads. EVAPORATOR The lamellar and solder heat exchanger from corrosion-proof AISI 316 steel. Two independent contours on the party coolant and one on the party of water. CONTROL UNIT Components: relay of control of phases, controller, introduction switch, protection devices compressors from an overload, protection on low and high to pressure in a refrigerating contour, on forcing temperature, on temperature of windings of the fan. Dry contacts for management of a chiller and signals "accident / work". CONTROLLER Continuous indication set and actual heat carrier temperatures, real time, loading percent on a chiller, work / accident / blocking. Rotation of compressors and pumps on an operating time, maintaining the magazine of emergency states with date and time of emergence, maintaining the magazine with an operating time of compressors, pumps and the general operating time of a chiller. It is in addition completed with the portable control panel for remote change of parameters and operating modes. Possibility of connection to system schedulings of buildings of BMS. |
REFRIGERATING CONTOUR
Components: the relay of low pressure, the relay of a high pressure with manual return to a working condition, sensors of high and low pressure, relay protection on forcing temperature, the filter dehumidifier, viewing glass, the solenoidal gate, the temperature-controlled gate with external equalizing of pressure, service valves of Schröder. WATER CONTOUR The contour is built on demountable gruvlochny connections. Components: sensors temperatures of the entering and leaving heat carrier, the channel relay, automatic airby-pass the valve with the gate-type valve, the safety valve with drainage branch. EXECUTION TYPES 00 - Without pumps; 1A - One built-in low pressure circulation pulser and a broad tank; 1B - One built-in medium-pressure circulation pulser and a broad tank; 1C - One built-in high-pressure circulation pulser and a broad tank; 2A - Two built-in low pressure circulation pulsers and a broad tank; 2B - Two built-in medium-pressure circulation pulsers and a broad tank; 2C - Two built-in high-pressure circulation pulsers and a broad tank. THE OPTIONS WHICH ARE BUILT IN U1 - control of one pump (it is established out of a chiller); U2 - control of two pumps (are established out of a chiller, rotation on an operating time); The EU - a payment of the consecutive Ethernet interface (Web Server); LW - a payment of the consecutive LonWorks interface; MV - the card of the consecutive RS485 (Modbus) interface. CONNECTION TYPE V - gruvlochny in accordance with GOST P 51737‑2001; G - cylindrical pipe carving in accordance with GOST 6357‑81; F - flange in accordance with GOST 12815‑80. By default chiller are delivered with a conic pipe carving in accordance with GOST 6211 (it is not specified in marking). |
