Air-conditioner makers in Japan have been working on some new functions with the coronavirus in mind. Their latest models feature innovations that can keep a room's air fresh.
Daikin Industries will launch a model next month that can bring in air from outside to stop a room turning stale. The company says the redesigned condenser can ventilate as it cools or warms a room.
Johnson Controls-Hitachi Air Conditioning has come up with units that use AI to estimate the carbon dioxide density of a room and tell users when they should open a window.
Sales of home-use air conditioners in Japan hit a record high last year as people stayed home more. But the demand has leveled off this year.
