Bosch is now offering not only heating, hot water and ventilation solutions, but also VRF (Variable Refrigerant Flow) systems for efficient air conditioning in commercial buildings. Thanks to variable refrigerant flow technology, the new Bosch VRF air conditioning systems are convenient and save valuable energy at the same time. They adapt their performance to current demand and therefore also work with outstanding efficiency under partial load. The systems consist of outdoor units and several inside units and can be utilised for both cooling and heating.
Full DC Inverter Mini VRF with DC inverter compressor and DC fan motor delivers a highly efficient solution for small commercial buildings. Four to twelve rooms require only one outdoor unit, and individual control is enabled in each room.
Intelligent Manager of Bosch, designed specifically to control VRF systems, is based on a centralised format and dedicated to the complete control and monitoring of all the system’s functions. It can be used as a flexible multi-purpose system and applied to a variety of needs, according to the scale, purpose and control method of each building. To meet designers, consultants and installers requirements, Bosch has developed an advanced design automation tool that can be used in AutoCAD-based CAD version or Windows-based version. The software provides quick and convenient selectable options for users, supports multiple languages, and greatly improves the selection process.
Bosch VRF air-conditioners for efficient airconditioning in commercial buildings. The Bosch Climate 5000 VRF has many key technologies resulting in highly improved performance - excellent cooling/heating performance, comfort, reliability and easy installation.
New products recently launched by Johnson Controls include Hitachi Sigma range of Variable Refrigerant Flow (VRF) systems, the York YZ Magnetic Bearing Centrifugal Chiller, the smart Glas thermostat, the Hitachi Set Free ? range of indoor and outdoor cooling and heating systems, and the YZ Magnetic Bearing Centrifugal Chiller.
Samsung Electronics Co. Ltd. unveiled its latest innovations in Heating, Ventilating and Air Conditioning (HVAC) engineering during a roadshow which started in Cape Town, on the 8 March, 2016, followed by a roadshow in Zimbali, KwaZulu-Natal on 11 March 2016 and an event at Montecasino, Johannesburg on 16 March 2016.
The high price tag of even entry-level chillers has made this market segment very competitive. Johnson Controls’ Amichi Series of Chillers and Heat Pumps, introduced to the South African market just six months ago, offers a high value option, featuring a technology stack and performance that is hard to beat.
The Amichi range meets or exceeds the requirements for the Ecodesign regulations for heat pumps, comfort chillers and process chillers through an optimised combination of YORK efficiency-enhancing technologies.
