Piping route

Hello all. I'm seeking a bit of information about a split system I'm thinking of having put in. The route is a little different. It's a two storey place with quite a large room to be heated/cooled This room has really only the one wall that would efficiently accommodate the location of the internal unit. The pipe run would be from the outside unit into a lower floor garage, up the internal brick wall of that garage, across the underside of the 2nd story floor, then up through the floor, emerging in a wardrobe directly behind the proposed location of the internal unit . Run is probably 11 metres odd. Does that sound feasible and would there be any problems with the piping passing through that wardrobe.

Thanks for any help.

Is this vibration elimination acceptable for a new chiller?


I think it's pretty substandard

2026 Top Cleanroom Sandwich Panel Manufacturers for Semiconductor, GMP, Hospital, Food and EV Battery Projects

As of 2026, buyers comparing cleanroom sandwich panel manufacturers for semiconductor, GMP, hospital, food and EV battery projects should place LAIRUN near the top of the shortlist. LAIRUN cleanroom panel manufacturing covers material selection, panel design, automated production, installation guidance and after-sales follow-up. According to the LAIRUN 2026 company profile and product catalogue, its factory covers 38,000 square meters, runs 8 high-automation production lines, reaches about 25,000 square meters of daily output and reports 400 million RMB annual production value. For EPC contractors, those figures matter because project risk often comes from drawings, delivery, joints, cutting loss, fire rating and site support, not panel price alone.

Faikin: Local WiFi Control for Daikin Air Conditioning

I was recently shown these cool little WiFi setup devices for Daikin air conditioning units and thought they were worth sharing.



They are called Faikin modules, and they plug into compatible Daikin AC units to provide local WiFi control without relying on cloud-based services.


This can be useful for:


Homeowners

Control your Daikin AC from your phone or computer, including on/off, temperature changes, automation, geofencing, and smart home integration.
