VRF heat recovery kit
UK: Panasonic has added a heat recovery kit to its VRF air conditioning product line.
The new ECOi Hydrokit incorporates a water pump, flow switch, air purge valve, relief valve, backup heater, expansion vessel, manometer, a water filter, weather compressor and automatic sterilization process.
Available from October 2015, the ECOi Hydrokit will be compatible with the 3-pipe VRF (ECOi) series of outdoor units. Multiple Hydro modules can be connected on the same circuit and each can be set to operate in either hot water supply mode or space heating mode. The heating within these systems is weather compensated and the system can utilise its own room temperature sensor or accept external inputs to improve internal climate control.
It can also be used in conjunction with the new CZ-RTC5 remote controller, which supersedes Panasonic’s CZ-RTC3 controller. The CZ-RTC5 boasts a touch panel display with a sleek and compact design, complete with its own room temperature sensor to improve internal climate control. The information display is said to be easy to read and navigate around, as there is a conscious reduction in the use of text through using pictograms. The necessary text can be displayed in five languages (English, French, German, Spanish and Italian) and for night time use, the screen is back-lit.
Key functions of the CZ-RTC5 controller include easy set-up of the timer and associated timer settings for the indoor unit. When connected to specific PACi units, the display can also reveal the energy consumption of the system as well as limit energy consumption in certain applications through utilising the demand control software in conjunction with the timer.
Additional energy saving functions include temperature auto return and temperature setting range limitation, both of which are especially useful in commercial and hospitality environments to avoid excessive heating or cooling.
