ZFKQ for Refrigeration Applications

Product catalogue

1

Emerson developed the ZFKQ range of Copeland Scroll™ compressors to provide the best performance in low
temperatures. The series has a wide application envelope that can operate from -40°C to +7°C evaporating
temperature. Its optimized design perfectly fits frozen food application requirements while its scroll
compliance mechanism makes it highly tolerant of liquid slugging.

The range consists of:

• The ZF*KQE models that operate with liquid injection in order to control discharge temperature and
extend the operating envelope.

• The ZFI*KQE models that are optimized for vapor injection with the use of a subcooler. This boosts the
refrigeration system's cooling capacity and efficiency.

Features and benefits

High efficiency all year round

• The unique Copeland Compliant Scroll design patented by Emerson operates under continuous scroll flank
contact, maintained by centrifugal force. This minimizes gas leakage while maximizing efficiency.

• With its capability for condensing operation down to 4°C on low temperature applications, Copeland
Scroll technology provides the best seasonal efficiencies.

• Equipped with dynamic discharge valve that allows the discharge gas to reach desired pressure. This helps
reduce efficiency loss by preventing gas re-compression.

• The vapor injection technology allows ZFI*KQE compressors to perform higher efficiency than single-stage
compressors at low temperature operation condition. Thus makes ZFI*KQE the best in-class performance.

Compactness

• The small footprint of Copeland Scroll compressors enables compact system designs.

• Weight and dimensions for refrigeration equipment is reduced with increased capacity per compressor
weight.

Robustness and reliability

• The Copeland Compliant Scroll design is tolerant to stresses caused
by liquid slugging, flooded starts and debris commonly found in
refrigeration systems.

• Easy to service and maintain due to their compact size and lightweight,
simple design.

• Engineered for optimum performance with today’s chlorine-free
refrigerants.

• The Copeland Scroll compressor design has several inherent reliability
advantages:

- 70% fewer moving parts than reciprocating compressors

- Axial & radial scroll compliance provides improved liquid handling
capability

- Hermetic design reduces leak potential

• Redesigned suction gas flow results in lower oil circulation and better
motor cooling.

Control kits provide advanced features to ensure

Compressor protection

• ZF*KQE and ZFI*KQE compressors are supplied with internal thermal protectors that prevent motor
overheating in case of loss of phase or low refrigerant charge.

• The ZF*KQE models that operate with liquid injection through DTC Valve in order to control the discharge
temperature.

• The ZFI*KQE models that can operate with Emerson EVI CoreSense
injection superheat as well as a safe discharge temperature.

Smooth operation

• All Copeland Scroll compressors are designed with a discharge check valve that isolates the high pressure
discharge gas. This allows the compressor to start unloaded, resulting in low inrush currents.

• Smooth operations are made possible by the continuous compression process. This generates less vibration
than reciprocating technology.

Delivers unmatched energy efficiency: 5%–20% improvement

• Motor, scroll and bearing redesign minimize annual energy consumption.

• Precision machined scrolls provide the highest isentropic efficiency and wear-in for improved performance
over time.

• New valving technology adjusts the scroll compression ratio based on operating condition, significantly
improving low ambient performance.

• Using vapor injection improves system capacity by 50% and efficiency by 20% on average at the low
temperature rating condition.

One model for multiple refrigerants

• All ZF and ZFI compressors are qualified for R22, R404A, R507, R407A/C, R407F, R448A, and R449A.

EVI CoreSense™ control kits and wiring diagram

EVI CoreSense control kits

Introduction

The EVI CoreSense control kit of ZFI compressor is intended to control vapor injection, maintain a safe discharge temperature,
and provide intelligent diagnosis and protection.

The kit includes a printed circuit board (PCB), an electronic expansion valve (EXV), and three sensors, as well as containing a
transformer and an EXV filter. All parts are common, except the EXV valve orifice size, which will be applied to different ZFI models.

In vapor injection application, the valve is driven by sensors mounted near the heat exchanger and attempts to maintain
the vapor outlet sensor 5K higher than the vapor inlet. The system will switch to discharge line temperature control if vapor
injection is insufficient to maintain a safe discharge temperature. If the discharge temperature becomes dangerously high, the
system will stop the compressor, turn on an LED alarm, and trigger a voltage free alarm relay contact. The compressor can auto­reset, but not lockout.

Emerson provides customer EVI CoreSense control kits with and without CoreSense box.

Printed circuit board

Wear a ground strap when working with the PCB to avoid the risk of damage from static discharges.

General PCB layout, input and output ports are shown in the image below, the ports to EXV, DLT, as well as the vapor in and
vapor out sensors are done with Poka-yoke connector design. Connect sensors, EXV, and system wiring as shown in wiring
diagram.

The PCB is supplied power through a transformer with a power input of 50/60 Hz, 220VAC, and an output of 12VAC to the PCB
board.

For EVI control kits with CoreSense box, the board and transformer are both mounted in the box, using 4 x Ø5mm holes at
61 x 101mm centers, fastened by screws. Spare part number is 543-0189-01 for field service.

For EVI control kits without CoreSense box, we provide individual parts for compact system design. The board is with 4 x Ø4mm
holes at 61 x 101mm centers, please use plastic stakes provided. Spare part number is 543-0219-01 for field service.

Dip-switch setting

The dip-switch default setting has been done in-factory, please do not change setting and ensure that the replacement board
is set correctly.

For the glide-refrigerants application like R407A, R407F, R407C, we would recommend 10K superheat. Please contact your
local Emerson sales and application engineer to reset the dip-switch.

Temperature sensors

The EVI kits include 3 temperature sensors. Please ensure all sensors are mounted in the correct locations, fastened, and
insulated properly.

The discharge temperature sensor should be installed approximately 178mm (7 inches) from discharge tube outlet. If a service
valve is installed at the discharge tube, the sensor should be located 127mm (5 inches) from the valve braze.

The vapor-in sensor is connected to the pipe between the EXV and PHE. The vapor-out sensor is connected to the pipe from
the PHE to the compressor vapor injection port. Don’t make the vapor-in and vapor-out sensor location reversed.

and Ø1.8mm depending on system size, applied to different ZFI models.

The liquid refrigerant should pass from the bending tube and flow out from the straight tube. Please weld the filter before the

to compressor

Mount plate heat exchanger in the vertical position and
oriented correctly. Ensure that sensors are located correctly
as well.

ZFI vapor injection compressors can deliver very cold liquid
with economizer cycle. The sub-cooling of liquid line calls for
these recommendations:

1. Liquid line pipe connecting the economizer to the
evaporator expansion valve should be well-insulated
separately.

2. The lower liquid line temperature can increase the
evaporator valve capacities. Please follow the valve
manufacturer's recommended liquid temperature
correction factors for proper selection of evaporator
expansion valve. Refer to product catalogue or select

software for liquid line temperature.
