heat exchangers and freezing
Hi All,
I would appreciate your advice with regards to the heat exchangers for the office building, with vrv system designed for outside temp. -12C, inside t 22C, humidity 50%, but the outside temperature could get during the nights to -18C. They will be placed 8-10m inside the building. Are they going to freeze and if yes, for how long we will not have a fresh air? Do we need an additional heater for the fresh air? Is it sufficient to use a device with paper heat exchanger to lower the humidity and potential risk of freezing? thanks in advance
