Perfect operating air cooled package unit for industrial use

Product introduction

Air cooled modular chiller is a kind of central air-conditioning unit which adopts air as the cooling or (Heating) source and water as the cooling or (heating) medium to cool down or (heat ) the indoor ambient temperature through the indoor terminal(AHU/FCU). Air cooled chiller typically have a lower initial investment and maintenance cost than water cooled system since it does not require a cooling tower, condenser water pump, and associated condenser water chemical treatment system. air cooled package unit

Modular design concept makes the application from single unit to multiple form systems to several thousand tons of installed capacity.Adopting high reliable and excellent efficiency system Midea air cooled scroll become one of the best choice for all kinds of air cooled projects. With the latest modular design technology, high efficiency V shape heat exchanger and precise gas flow control technology and digital compressor application, Midea air cooled scroll chiller system always work at the most high efficiency stage. Modular and compressor operation are adjusted by the real load requirement intelligently to keep the most economical working status.

Features and benefits

Outstanding reliability

Excellent efficiency

Design flexibility

Easy for installation, simple for maintenance

Modules connect easily and quickly

Wire controller used for easy setting and operation

DIGITAL SCROLL COMPRESSOR

A scroll is an involute spiral which generates a series of crescent-shaped gas pockets between the two members( fixed scroll and orbiting scroll). In the digital scroll compressor the controlled separation of the scrolls is achieved using a solenoid valve and a bypass connection between the discharge chamber and the intake gas. The scrolls are designed so that the upper scroll can separate from the bottom scroll by

1mmvertically. A piston is attached on top of the upper scroll and will lift up the upper scroll when it moves up. When the solenoid valve is closed, the Digital Scroll operates as a normal Scroll compressor and the compressed gas is discharged at high pressure through the normal piping. When the solenoid valve is opened, the discharge chamber and intake gas pressure becomes connected, thereby releasing some of the discharge pressure.

General information

Units ship with a full operating charge of Zero Ozone Depletion Potential refrigerant R410A and oil.

Air-cooled condenser

The air cooled condenser coils with V-shaped consist of staggered rows of 3/8" OD seamless copper tube, mechanically expanded onto die formed aluminum fins to ensure optimum heat exchange capability.

Evaporator

The smaller module lower than 35kW mode adopts the tube in tube heat exchanger for the compact design. Capacity from 55kW to 200kW modes adopt shell and tube heat exchanger for easy maintenance. High efficiency, direct-expansion type cooler with refrigerant in tubes and chilled liquid through the baffled shell without any of the oil return problem comparing with flooded type evaporator. Design working pressure of the shell waterside is 1Mpa, and 2.4Mpa for the refrigerant side. Working pressure of 1.6Mpa or 2.0Mpa is optional. Water baffles fabricated from galvanized steel to resist corrosion. Removable heads allow access to internally-enhanced, seamless, copper tubes. Water vent and drain connections included.

Wide range of outlet water temperature
