The City of Vancouver will likely approve a new bylaw in October banning OTC cooling systems for walk-in refrigeration and HVAC units of 5 ton or greater capacity.
Owners and landlords are recommended to inspect leased and rented restaurant, bar and food preparation spaces in advance of the new bylaw's passage.
Areas of concern when inspecting tenant spaces are walk-in coolers, and under-counter bar fridges that have a pipe leaving the unit being either connected into sanitary or concealed in a drain.
It is unlikely you will find this sort of cooling system for fan coils or heat pumps in your buildings, unless there is a small office that is a far distance away from the chilled water distribution in a building.
If you find this sort of system, please advise your tenants that in 2017, they will need to replace their fridge or cooler with an air cooled system and to plan for it accordingly.
