Honeywell’s Solstice ze (R1234ze) has demonstrated increased effi ciency over ammonia (NH3
) in a study in France that analysed both
refrigerants in the use of chiller applications. The project, commissioned by French company Quercy Refrigeration was conducted by Optinergie, a consulting company that specializes in energy performance, at the Aiguillon Fruit Cooperative (COFRA) in southwest France. In a side-by-side comparison, R1234ze outperformed NH3

in chillers
by 25% according to the energy effi ciency ratio (EER) analysis. The EER is determined by the ration between the cooling capacity produced and the electrical energy consumed by the chiller. COFRA commissioned the study with the aim of reducing their annual electricity consumption, on average 300k€/year. In a detailed study, Optinergie measured various technical parameters and the electrical consumption of chillers (compressors, condenser, auxiliaries) for each chiller installation that used R1234ze and NH3
. Over the course of the study, the company obtained an
average EER of 1.72 for the R-1234ze chiller, compared to 1.29 for the NH3 chiller.

SWEP’s new BX4T model is the latest in the B4 sized range for the refrigeration market, with a more compact design than existing economisers targeting VRF, heat pumps and condensing units. The BX4T has the X-plates on front and back, giving the unit structural stability while also being active heat transfer plates. This All-Active plate pack maximizes the material utilization of the product, making it a highly competitive choice for demanding applications and narrow temperature approaches.
Stefano Bellada, SWEP segment manager for refrigeration said: ”The product is small, yet fl exible, which makes it a particularly good selection for economizer applications focusing on VRF and heat pumps. This new BPHE (brazed plate heat exchanger) provides supreme economizer performance, especially in condensing units with EVI- technology.”
The BX4T is also extremely eff ective in reducing refrigerant hold-up volume and its mechanical design makes it suitable for high pressure refrigerants such as R410A and R32.
The BX4T is one of the newest models to join SWEP’s full range of BPHEs engineered to deliver the highest COP and the lowest life-cycle cost. The applications include supermarkets and transport.
