PRODUCT DESCRIPTION

2 INTRODUCTION Compressors YORK Zafiro 410A chillers are designed for water or water-glycol cooling. The unit has suction-cooled, hermetic scroll compressors. High efficiency is achieved through a controlled orbit and the use of advanced scroll geometry. The compressors incorporate a compliant…

Refrigerant Circuits

Condenser (YCWL units only) Two independent refrigerant circuits are provided on each unit. Each circuit uses copper refrigerant pipe formed on computer controlled bending machines to reduce the number of brazed joints resulting in a reliable and leak resistant system. The twin-refrigerant circuit…

The microprocessor control includes

• Day, date and time • Automatic control of compressor start/stop, anticoincidence and anti-recycle timers, automatic pumpdown on shutdown, evaporator pump and unit alarm contacts. Automatic reset to normal chiller operation after power failure. • Daily start/stop times • Remote water temperature…

ACCESSORIES AND OPTIONS

Soft Starters Factory mounted soft starters reduce the inrush current to the last compressor on each refrigerant circuit. They are preset so that no field adjustment is required. Power Factor Correction Factory mounted passive (static) power factor correction capacitors to correct unit compressor…

REFRIGERANT FLOW DIAGRAM

YCWL Low-pressure liquid refrigerant enters the cooler tubes and is evaporated and superheated by the heat energy absorbed from the chilled liquid passing through the cooler shell. Low-pressure vapour enters the compressors where pressure and superheat are increased. High pressure superheated…

INSTALLATION

Location Requirements To achieve optimum performance and trouble-free service, it is essential that the proposed installation site meet with the location and space requirements for the model being installed. For installation in equipment rooms near noise-critical areas, common walls should be of…

Pipework and fittings immediately next to the heat

exchangers should be readily de-mountable to enable cleaning prior to operation, and to facilitate visual inspection of the exchanger nozzles. Each heat exchanger must be protected by a strainer, preferably of 20 microns, fitted as close as possible to the liquid inlet connection, and provided with…

Condenser Cooling Liquid System

Refrigerant Relief Valve Piping The compressor, cooler and condensers are each protected against internal refrigerant over-pressure and fire by refrigerant relief valves. The pressure relief valve is set at the design pressure of the system and has discharge capacity required by the relevant…

Condenser Cooling Liquid Systems

Inlet Temperature Control (by others) For primary cooling of units, condensers are usually piped in conjunction with a cooling tower or a dry cooler, although in some cases they can be cooled by well water. For a cooling tower / dry cooler system, the simplest forms of control are to use fan…

CONDENSERLESS UNIT REFRIGERANT PIPING

Condenser Below Chiller General When the condenser is located below the chiller, the liquid line must be designed for both friction loss and static head loss due the vertical rise. The value of static head loss of 11.3 kPa/m must be added to the friction loss pressure drop in addition to all…

To ensure that no eddy currents are set up in the power

panel, the cables forming each 3 phase power supply must enter via the same cable entry. Temperature Cutout’ or any of the compressors are running or the daily schedule is not calling for a shutdown with the unit switch on. All sources of supply to the unit must be taken via a common point of…

Remote Load Limiting

Load limiting prevents the unit from loading beyond a desired value. The unit % load limit depends on the number of compressors on the unit. The load limit inputs to terminals 13 and 21 work in conjunction with the PWM input to terminals 13 and 20. Heat Pump Kit When the special quotation…

COMMISSIONING

PREPARATION Commissioning of this unit should only be carried out by Johnson Controls Authorised personnel. The unit On/Off switch on the front of the control panel has been set to the Off position at the factory. This switch must remain in the Off position, preventing running of the unit until…

Soft Start (Option)

Due to vibration during transport the soft starter internal bypass contactor may be in a undefined state. If the following procedure is not followed this may result in the compressor momentarily starting when the unit power is first turned on. IMPORTANT During commissioning or if the soft start is…

FIRST TIME START-UP

During the commissioning period there should be sufficient heat load to run the unit under stable full load operation to enable the unit controls, and system operation to be set up correctly and a commissioning log taken. Read the following section in conjunction with the MBCS Manual, then proceed…
