POSTCARD FROM MOSTRA


Mostra this year was as busy as ever and ACR News went on a fl ying visit to select just a small handful of highlights.


BSRIA


BSRIA gave presentations around the theme of global trends. Speaking of the global air conditioning sector, Anette Meyer-Holley, manager VAC&R & Private Client, highlighted that the size of the sector is more signifi cant than heating, renewables and building automation and controls systems (BACS) put together. After the global overall drop in sales in 2016 BSRIA has seen a recovery in 2017, with estimated total volume sales reaching 136 million AC units. Ms Meyer-Holley said: “Splits are the most signifi cant market globally, with sales expected to reach around 113 million outdoor units exclusive of VRF in 2017. China and Asia Pacifi c account for 70% of global sales, with China holding the dominant position on the market, hence what happens particularly on the Chinese market, has an impact on the global trends. VRF continues to do well with growth of over 20% expected in 2018 supported by the picking up of the overall construction markets that has seen a modest growth of 2% in 2017. These trends occur in the greater context of the uncertainty surrounding phasing out HFC refrigerant gases. There was a continued surge in refrigerant prices in 2017, with the price for fl uorite reaching a six-year high last year. In addition, tax implementations in Europe makes for a very uncertain 2018 with open questions on how the introduction of new refrigerants will impact on the availability and costs of units, and how much will this impact the prices of the actual AC units. It is certain that in the medium/long term this is not just a European issue and that changes will happen at a global level.”


Bitzer


Bitzer showcased the new Orbit FIT scroll compressor for improved effi ciency and capacity especially in heat pump applications. Bitzer Orbit scroll compressors operate at peak


effi ciency despite demanding conditions, helping to reduce system footprints thanks to their compact size and unique compound solutions. So


far, users have been able to choose from two families: Orbit 6 and Orbit 8. For increased market requirements, such as the F-gas Regulation and Ecodesign Directive, Bitzer has developed the new Orbit FIT (Flexible Injection Technology) series with economiser technology. It features an economiser function, which increases system effi ciency and capacity in both heat pump and air-conditioning applications. These scroll compressors follow the principle of interchangeability, as their connection sizes and overall dimensions stay the same compared to Bitzer’s standard Orbit versions when only the economiser connection is added to the compressor. It features an enlarged operation diagram, which is mostly benefi cial in heat pump systems. The Bitzer advanced header technology system enables system manufacturers to fulfi l the requirements of the Pressure Equipment Directive. This oil management solution simplifi es design work and reduces operating costs.


Clivet Carel


Carel focussed on its IoT range which works through cloud services. These services include APPLICA, the mobile app designed for the latest generation of smart controllers with integrated NFC and Bluetooth connectivity. Confi guration and optimisation of unit set-up are made simple and intuitive by the combination of smartphone application and web portal, allowing confi gurations and graphics to be managed fl exibly and always kept up-to-date.


Also on show was the MPXone, Carel’s latest controller for food retail refrigeration units. It has many connectivity options that simplify human-machine interaction using APPLICA. MPXone also comes with several energy saving features that can even be activated in simple applications, allowing management of the most high-effi ciency modulating devices.


Carel had the new k.water & k.air range of products for integration, control and monitoring of HVAC systems on display. These controllers are designed to manage every part of the system.


Clivet was promoting its Smartpack2 (CKN-XHEi): Full Inverter high effi ciency autonomous air conditioners for medium and small sized retail applications. Smartpack2, with air fl ow-rate from


890 to 2915 l/s, is a plant integrated in a single unit which satisfi es the needs of air treatment, purifi cation and renewal in individual stores, showrooms, outlet villages, bars and restaurants, petrol stations, technical rooms and production areas.


Also on display was the (pictured) Sphera (SRHM+MDAN-XMi): air to water heat pump. This unit ranges from four to 16 kW in two sections for heating, cooling, domestic hot water production in class A++ and A+++.


Sphera is suitable for single and multi-family houses with low- medium energy consumption. The unit is very compact: external unit dimensions are reduced by more than 30%, and the Sphera-i recessed unit depth of only 35 cm. In order to satisfy every need Sphera is available in fi ve versions – inverter heat pump, cased and uncased inverter heat pump with integrated tank, cased and uncased inverter heat pump with integrated tank and boiler.
