SWEP Hypertwain^TM

First introduced in 2022, SWEP Hypertwain technology revolutionized the concept of what a brazed plate heat exchanger could do. The ancillary ports on SWEP Hypertwain enable optimized reversible operation in both heating and cooling duties, with a minimal refrigerant charge, lower energy consumption, and an extremely small footprint.

Improved control

Unlike a standard BPHE, a SWEP Hypertwain BPHE offers improved performance control, with the evaporator and suction gas heat exchanger (SGHX) combined in a single unit. SWEP Hypertwain also improves the temperature approach in reversible operation and generates high superheat, without impacting the evaporation temperature.

True reversibility for heating and cooling systems

More and more heat pumps and chillers are intended to be used in reversible mode. The reversible mode is a challenge due to co-current operation in the heat exchanger and results in a limiting effect by the superheat in the evaporator. The consequence is lower performance and thus higher energy usage in reversible mode. SWEP Hypertwain was designed to address these challenges.

Benefits of SWEP Hypertwain include:

Lower total cost of ownership
Reduced energy consumption
Smaller volume of refrigerant in the system
Compact design with less use of material
Minimal system footprint
Enhanced safety from reduced refrigerant charge
Reduced carbon emissions due to optimized use of material and refrigerant

An unbeatable combination

SWEP Hypertwain BPHEs make it possible to reap the benefits of an SGHX while avoiding the disadvantages. A SWEP Hypertwain BPHE is built with a dedicated zone for evaporation and a small area near the outlet port that is optimized for superheating the refrigerant. This zone acts as an integrated SGHX (iSGHX).

 This design makes more efficient use of the plate, requiring only 5% of the area to superheat the refrigerant gas, as opposed to a conventional evaporator, which requires approximately 30%. Optimizing the plate in this way increases the area of the plate that is available for evaporation. The resulting increase in the evaporation temperature improves the overall efficiency of the system. Solving the challenge of superheating makes it possible for SWEP Hypertwain to operate as a co-current flow evaporator at all times.

Optimized heat exchange in both heating and cooling

Solving the challenge of superheating makes it possible for SWEP Hypertwain to operate as a co-current flow evaporator at all times, which means that when the system is reversed, SWEP Hypertwain acts as a condenser with a counter-current flow. Unlike conventional BPHEs, this co-current evaporation flow optimizes heat exchange in both heating and cooling.

When SWEP Hypertwain operates as a condenser, the liquid flow to the SGHX switches off, and the unit operates like a conventional BPHE condenser. As a result, a system with SWEP Hypertwain heat exchangers is efficient in both cooling and heating.
