Keeping the room temperature between 72-80 degrees will ensure their comfort. Temperatures that are too high, or low, can stress the rats and lead to health problems. Laboratory guidelines for temperature are 20-26 degrees Centigrade (68-78.8 Fahrenheit). For breeding situations the recommended temperature is 24-26 degrees Centigrade (75.2-78.8 degrees Fahrenheit).
The requirement is still in place to keep the room at a target of 50% RH to reduce the risk of nosocomial infections. To keep the room at 50% relative humidity with the air temperature at 60-64F will require the air to be at a dew point temperature of 40-42F when delivered to the room.With the typical hospital having chilled water at 42-44F, this new requirement is impossible to achieve with what equipment is in place.t recommends the operating room air temperature be 68-75F with a 30-60% relative humidity. To get this condition the air flow is dictated by a recommendation of 15 total air changes per hour, ACH, with 3 air changes per hour with respect to outside air.
