DC Inverter Invar S Series | Outdoor Units

Model: APEA-252(8)X/E2SZ1U(D) APEA-280(10)X/E2SZ1U(D) APEA-335(12)X/E2SZ1U(D) APEA-400(14)X/E2SZ1U(D) APEA-450(16)X/E2SZ1U(D)

The all DC inverter INVAR heat recovery series, which can offers simultaneous cooling and heating operation in one system. The energy by-product from cooling or heating is transferred to where it is required by using the balanced heat exchanger function, which saves up to 50% in costs compared with a conventional heat pump system.


Technical Specifications

Wide Application Range

Wide Range of Outdoor Units

The outdoor units’ capacity range from 8HP up to 64HP in 2HP increment. Maximum 64 indoor units withcapacity up to 130% of total outdoor units can be connected as one refrigeration system.

Long Piping Length

The solution supports an incredible piping length of 1,000m and level difference of 110m, making it perfect forlarge projects.

Wide Operation Temperature Range

The INVAR S series system operates stably at extreme temperatures ranging from -20°C to 48°C.

High External Static Pressure

Max. 60Pa external static pressure can be customized for theoutdoor unit, flexible to build-in installation.

A standard 0-20Pa external static pressure is equipped by defaultfor all outdoor units. 20-40Pa external static pressure can becustomized for 14, 16HP outdoor units, and 20-60Pa can becustomized for 8, 10, 12HP outdoor unit.

High Efficiency

High EER

Heat recovery is achieved by diverting exhaust heat from indoor units in cooling mode to areas requiringheating, maximising energy efficiency, reducing electricity costs and leading to high partload efficiencies (up to7.0 in the 8HP catagory).

All DC Inverter Technology

All DC inverter compressors make the capacity output better distributed, and always work at 60-140Hz whichis the most efficient range. It makes the efficiency more than 30% higher than the normal.

According to the running load and system pressure, the system controls the speed of DC fan to achieve theminimum energy consumption and best performance.

Heat Recovery, More Efficiency

Simultaneous heating and cooling in different zones, more energy saving by heat recovery from one space toanother which saves up to 50% in costs compared with a conventional heat pump system.

Heating Capacity Automatic Adjustment

Two parts condenser individual design, the unit can distribute a part of evaporator to be as condensing areaaccording to the heating load requirement to improve the utilization rate of the condenser.

Enhanced Comfort

Cooling and Heating Simultaneous

Auto Mode Control

Continuous Heating During Defrost Operation

Easier Installation and Service

Remote Addressing

Simple Communication Wiring

Professional Structure Design for Easy Maintainence
