Modular heat pump,
STANDARD MCU-YH series

The STANDARD generation of MCU-YH modular air-to-water heat pumps features enhanced controls and microprocessor-based architecture, resulting in extended range of cooling and heating operation and improved adaptability to modern comfort demands. You can combine maximum 16 heat pumps units to obtain a total capacity of 60 kW to 2080 kW

Operation limits

The heat pump operates down to -15 degrees in heat mode and up to + 48 degrees in cold mode.

High efficiency, power saving and environment protection

The heat pump uses an eco-friendly refrigerant R410A. It is a chlorine-free, stable and non-toxic refrigerant that does not deplete the ozone layer, being safe for the environment. This refrigerant ensures efficient heat transfer, which means higher capacity of the modular heat pump and lower power consumption.

Modular Design

The unique feature of the series is its modular design with the ability to combine up to 16 modules (165YH, plus up to 8 modules) in a single system.

This feature allows extending the capacity over 1 MW with the number of capacity stages being equal to the number of compressors, so that you can have up to 32 capacity stages with 16 chiller modules (in dual-compressor models). The entire system is controlled via a single remote controler connected to the master module, while the rest are slave
modules. This results in a N-module monoblock heat pump.

Floating master heat pump

Any individual heat pump can operate as a master pump: you just need to connect it once to the wired controller. This eliminates the problem of the entire system going out of service, when the master heat pump fails.
 

High-efficiency fans

Metal fan blades with saw-shaped edges ensure increased air flow rate and high strength along with low noise level. The fan motors with IP54 rating ensure safe and reliable operation even in harsh weather.
 

Intelligent defrosting

The controller detects the current extent of freezing by analysing the air flow rate, temperature drop and refrigerant pressure in the outdoor heat exchanger.
In the first method, defrosting is periodically enabled and disabled on a timer. In the second method, the start of defrosting is coordinated with a sensor located outside the heat exchanger.
 

Ease of maintenance

Turning off one of the modules does not stop the entire system. As a result, you can repair, troubleshoot/service, replace or even add any module at any time, while cooling or heating the facility without interruption.
 

Powerful protection

The heat pump is equipped with powerful protection, including a self-diagnostic feature that ensures longlived, steady and reliable operation. The heat pump can be set to quickly resume the current operation after power recovery.

  • Compressor overload protection
  • High / low pressure protection
  • High / low voltage protection
  • Water shortage protection
  • Compressor short-cycling protection
  • Fan motor overheat protection
  • Power supply protection
  • Exhaust temperature protection
  • Outlet water temperature protection

Control system

The heat pump is equipped with a 3rd generation microprocessor-based control system and a state-of-the-art remote control. The modular control system built into the heat pump features USB ports for easy maintenance and upgrade of the control software.

Modbus

The Modbus board is included as a standard, so that the heat pump can be connected to either new or existing management system for convenient remote control and analysis via a PC.

Precise EXV

The heat pump is equipped with a 480-step EXV for precise refrigerant flow control. The patented control technology enables quick and accurate dynamic adjustment of the refrigerant level in the system based on the load changes, thus considerably improving the energy efficiency.

Shell-and-tube heat exchanger

The heat pump is equipped with a high-efficiency shell-and-tube water heat exchanger. The grooved inner surface along with a screw-shaped section improves heat transfer, while expanded fluid channels as
compared to a plate heat exchanger reduce the flow resistance and prevent the tubes from clogging. As a result, the shell-and-tube heat exchanger is less sensitive to water quality and more freeze-resistant.

V-shaped condenser

The heat pump is equipped with a high-efficiency shell-and-tube water heat exchanger. The grooved inner surface along with a screw-shaped section improves heat transfer, while expanded fluid channels as compared to a plate heat exchanger reduce the flow resistance and prevent the tubes from clogging. As a result, the shell-and-tube heat exchanger is less sensitive to water quality and more freeze-resistant.

The technology used prevents formation of ice, protecting the heat exchanger from freezing. There also is a gap between the heat exchanger bottom and the pan, which ensures free flow of the thaw water, thus improving drainage and preventing the water from accumulating and freezing.

Efficient scroll compressor

The heat pump is equipped with efficient hermetically sealed scroll compressors from world-renowned brands. Axial balancing and non-contact sealing of the spirals ensure frictionless operation and minimize the leakages. Radial balancing of the spirals allows foreign objects to pass freely through the compressor and protects the unit against both contamination and liquid ingress. This ensures higher compressor efficiency and reliable operation, as well as low vibration and noise levels.
