In fact, my wife has been in this exact predicament with several of her rescue orchids. Root rot can happen so quickly sometimes. The good news is that you can still save an orchid with few to no roots!
If the temperature is higher that -20Â° vs. outside temp, look for areas where air may be getting in and heating the house. However, with the thermostat set to cool, the air coming out of the air escape should be between 45-60Â°F. Locate the vent. In some cases they may be on the floor, wall, or ceiling. For vents on the ceiling, the IR-IND allows you to gauge temperature (from a distance) as it leaves the vent.
The energy cost of exhaust-only or natural ventilation versus energy recovery ventilation can be easily demonstrated. Take a 2,500-square-foot house with indoor conditions of 70Â°F and 40% relative humidity, and outside air conditions of 30Â°F and 50% relative humidity.Heating season function shown by flow arrows.). A closeup of the air-to-air heat exchanger core. The heat recovery ventilator (HRV) and its close cousin, the energy recovery ventilator (ERV), can often make a home more efficient.
