Modular heat pump
Inverter MCU-YHI series
The high-tech series of MCU YHI heat pumps from Mycond is made on the basis of advanced technologies. The heart of the unit is an advanced inverter compressor with EVI technology. Along with fans made on the basis of inverter technologies, microprocessor type of control and other components from world-famous brands, the heat pump guarantees uninterrupted operation all year round, both for cold to -20...55 C and heat to -26...55 C degrees.
It combines high efficiency with accurate and year-round maintenance of climate performance for any system
Full-inverter power saving
Energy efficiency class 1 according to the dual classification scheme based on the seasonal energy efficiency ratio (SEER) during cooling and heating operation. Power saving up to 26% in the entire SEER range.
34 -150 kW
Heating capacity: 33,5 - 130 kW
Cooling capacity :
Various applications
This solution is suitable for conventional indoor use, as well as special process and sanitary conditions, cooling only operation, low temperatures and extreme heat, etc. The unit supports a full range of alternative applications.
Intelligent combination
Up to 16 fixed-speed modules (YH\YHE) and variable-speed inverter modules can be freely combined. This allows meeting various project demands, such as energy saving.
All-round air intake
The heat exchanger is made of two U-shaped parts, with 45% more area on the air side and uniform all-round air return.
Proprietary drive control program
The unit is driven by a BLDC motor, while the control program with 8,000 counts per second and double filtering prevents power outages at any frequency level.
Inverter driven operation and precise output adjustment
The powerful inverter compressor supports stepless adjustment of capacity within 15% to 100%. It also performs well under partial load, avoiding frequent starts and stops. The use of EVI technology enables operation in extreme cold or heat.
Balancing management
Partial load takes priority during operation. When several units operate together, each compressor is frequency controlled through intelligent management, which ensures balanced operation in the energy-efficient area of the performance curve.
Technological design
- The heat pump components are completely concealed to prevent them from damaging
- Improved heat exchange efficiency thanks to the increased air intake area
- Sheet metal casing painted in ivory colour
- Distinctive inverter design with the technology of enhanced vapour injection (EVI)
- High-efficiency shell-and-tube heat exchanger
Communication and control features
- Modular design for easy combination of the units
- Easy to use touch control panel (accessory)
- Support of remote control via MODBUS
Partial load operation prioritized
When multiple modules are combined, the frequency of each compressor is intelligently controlled, with priority given to the operation in an energy-efficient partial load area. At the same time, compressor running time and load are balanced to facilitate uniform wear of each module compressor.
Patented 5-stage sound insulation for compressor room
- Acoustic block. Green felt with butyl rubber material to frequency noises
- Ultra-silence acoustic panel absorber. High-density foaming damping material to effectively absorb vibration and noise across frequencies
- Hermetic soundproof box
- Suction and discharge copper pipe, oil separator, silencer, etc., placed in the compressor soundproof box
- Protection panel around the unit to further block noise
Industry's largest diameter axial fan under equal air flow
Sawtooth large impeller, low rotating speed, low fan speed, operating noise in low speed for dual blower as 30 dB. The brushless full DC fan motor features stepless speed adjustment of 15-100% and more stable operation, achieving higher energy efficiency while reducing noises.
Frequency conversion and noise reduction
Three silent modes selectable
With wired controller settings, the unit automatically limits the operation frequency of the compressor and the fan and actively reduces noise to meet customers' higher requirements.
Operation range
Thanks to many years of experience in the development and design of refrigeration equipment, the company has successfully implemented the technology enhaced vapour injection (EVI) and inverter technology and made a breakthrough in the operation of modular heat pumps, the operating range is increased.
