AIR CONDITIONING
hange in our use of air ng climate change?
where it is used in order to off set solar gain. Indoor air quality is another area that can be improved with the benefi t of good quality air conditioning units employing high tech fi ltration to remove allergens and bacteria from the air, something that is becoming increasingly important as outside air quality deteriorates due to pollution and higher summer temperatures. In essence, the way we live in 2018 has increased our need for air conditioning. Cooling systems may already account for about 10% of total electricity consumption in the UK, according to the UK Building Research Establishment. It estimates that 65% of UK offi ce space and 30% of UK retail space was air conditioned in 2012, a fi gure that is set to increase year- on-year. The IPCC has projected that global air-conditioning energy
demand will grow 33-fold from 300 terawatt-hours (TWh) in 2000 to more than 10,000TWh in 2100, with most of the growth coming in developing countries such as India, Mexico, Indonesia and Brazil. In a world already warming because of fossil fuel emissions from oil, gas and coal, demand for air conditioning and refrigeration is widely viewed as one of the greatest accelerants of climate change.
So how is our industry tackling this issue?
Move to low GWP Japan’s Refrigerant and Environmental Conservation Organisation (JRECO) has recently announced a partnership with the United Nations Industrial Development Organisation (UNIDO) to identify and develop climate- friendly technologies, including accelerating the replacement of harmful refrigerants with
alternative low global warming refrigerants. Leading air conditioning manufacturers, such as Hitachi, have focused their R&D eff orts on eco-friendly refrigerants such as R32 which has a low global warming impact, using lower levels of refrigerant, and energy effi cient technologies such as human sensors, zone-by-zone individual control, super-effi cient compressor technology, commercial unit-by- unit electricity monitoring software and smartphone compatibility to allow remote control of domestic heating and cooling levels from anywhere.
Hitachi has been building its reputation of quality engineering for over 100 years, and the range of innovative heating and cooling products manufactured under the Hitachi brand for home, commercial and industrial applications is engineered for climate-friendly seasonal effi ciency.
