Keeping up with latest technology
Improvements in technology, more efficient power consumption and new models means there has never been a better time to install a Daikin heat pump, Refrigeration Supplies owner Hayden Sutherland says.
Refrigeration Supplies is a third generation Southland company which has a 20 year relationship with Daikin.
Daikin is the world’s largest air conditioning company and is always updating its units with the latest technology, Hayden Sutherland says.
Daikin heat pumps use a relatively new, more efficient refrigerant which operates at higher coefficient of performance, the ratio between the heating or cooling power input and capacity output; higher COP’s equate to lower operating costs.
“Daikin are the most energy efficient heat pumps in Australasia,” he says.
With a seven star Energy Star rating, depending on the model, power input of 0.62 of a kilowatts produces up to 3.6 kilowatts of heating output.
A new floor mounted model now available, Nexura, features state-of-the-art heating technology.
“It is the only heat pump of its type on the market that is capable of radiant heating.”
Because the radiant heat is still created by refrigeration technology Hayden says that there is no difference in power consumption to conventional heat pumps.
Daikin’s US7 model is unique in that it also offers both humidification and dehumidification functions.
For tech savvy users, Daikin’s D-Mobile app enables a smart-phone or tablet to operate a wallmounted heat pump unit via Wi-Fi or the internet from virtually anywhere, which means a home can be warmed before its occupants get in the door at any time of the day or night.
Hayden says it is important for people to get professional advice about installation.
Common traps are installing heat pumps which are too small for the area they are heating or incorrectly positioned indoor and outdoor units.
In the commercial sector Refrigeration Supplies has decades of experience in the the design, installation and service of refrigeration needs for a wide range of applications for water chilling equipment, cool stores, display cabinets, hospitality, supermarkets, marine and dairy farm milk cooling.
The company is the designer of the patented DUCK – dairy unit cooling kit – system.
Refrigeration engineer Lance Jefcoate says the DUCK system covers a vast range of equipment for many applications within the dairy sector.
He believes there are advantages, such better flexibility to upgrade, for clients in dealing with a local company which has custom designed a system from scratch.
“Not every farm is identical in its makeup. We get a lot of farms that will start off in the first year with 500 cows and the next year they are milking 700 or 800 cows.”
“We take that into account when designing and building a new unit, but we also take into account future expansion needs as well.” There is increasing awareness among farmers of the energy consumption of their refrigeration systems.
Because milk cooling accounts for about 30% of the total energy costs of operating a dairy unit, Refrigeration Supplies is always looking closely at enhancing the efficiency of the systems.
It is presently designing a DUCK system based on the need for dairy farmers to meet upcoming Ministry of Primary Industries rule changes effective from June 1 2008 for cooling milk to specific temperatures within specific time-frames.
