Product Features

 Due to the multi-system optimised design of the high-performance DC inverter hermetic scroll flexible compressor, the unit's performance ratio (EER value) can reach more than 5.0 for cooling and more than 4.5 for heating under the calibrated working condition.

Good part-load characteristics

The unit can operate normally under the condition of small cooling output, the microcomputer control system of the pro-machine can flexibly and reasonably control the number of module operation, and the cooling capacity of each module of the same amount can be automatically adjusted by the internal inverter compressor, and it can operate efficiently even in the range of low load, so that the unit's output of cooling capacity can be optimally matched with the demanded cooling capacity to maximise the energy saving.

In addition, for the commercial buildings and office buildings which are leased (sold) or used in different levels, in the case of needing to provide very small cooling and heating loads individually, the use of traditional central air-conditioning units will give rise to the situation of a big horse pulling a small car, which is not only a big waste of energy consumption, but also a big harm to the unit, and the strong point of the modular unit is to deal with such a situation.

Small and compact (especially suitable for renovation work)

The modular design concept is integrated into every part of the unit and every pipeline, and the core components of the unit are compactly and reasonably arranged.

The arrangement of the core components of the unit is compact and reasonable, and the unit is small in volume and light in weight (a single module weighs only 280-560kg).

At the same time, the unit is not limited by the external conditions of construction and can be moved at will, which is especially suitable for the use of renovation projects.

◆ Excellent selection of components for modular units

The use of shell and tube heat exchanger, the heat exchanger's small size, safety and no leakage, high heat transfer efficiency, heat loss and Yin force loss is small, easy and quick maintenance

Wide range of applications

The unit is applicable to a wide range of water source temperature: 8-35℃. It can provide both hot and cold water of 7℃ or 45℃ for air-conditioning and 50℃ for domestic hot water. In addition, the high-temperature type unit can provide hot water up to 60℃, which can be directly used in the original radiator heating system.

Full range of safety and protection features

Pressure protection: high pressure protection and low pressure protection device.

Motor protection: loss of voltage protection, phase shortage protection, reverse phase protection, motor overheating protection.

Anti-freezing protection: when the temperature of chilled water is too low, the unit stops.

Safety valve protection: when the refrigerant pressure exceeds a certain value, the safety exhaust valve will open automatically.

Various protections of the above equipment make the unit run safely and stably.
