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 heat pump featuring eco-friendly refrigerant R410A with modular design for high efficiency.

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.

 

 

An individual heat pump connected to a wired controller, capable of operating as a master 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.

 

 

 

Metal fan blades with saw-shaped edges for increased airflow and low noise.

 

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 outdoor heat exchanger temperature sensor.

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.

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.

The V-shaped air heat exchanger enhances airflow and heat transfer efficiency.

 

V-shaped condenser

The special V-shaped design of the air heat exchanger provides increased air flow, while hydrophilic aluminum fins and corrugated inner tubes improve the efficiency of heat transfer. Metal fan blades and mesh grilles provide greater reliability and protection against external impacts. A check valve installed in the refrigerant circuit at the bottom of the heat exchanger prevents circulation of low-temperature refrigerant in the heating mode, while enabling circulation of high-temperature refrigerant in the defrosting mode. This prevents formation of ice, protecting the heat exchanger from freezing.

 

 

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. This ensures higher compressor efficiency and reliable operation, as well as low vibration and noise levels.

Operation limits

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