I am a national lifeguard, working at an outdoor pool. Temperature should be between 74 ~ 80. If it's over 80 degree, there is possibly a great chance of bacteria growing.
weather and time my friend...weather and time.
The outdoor thermostat in a heat pump system helps regulate the system's operation based on the outside temperature. It ensures the heat pump runs efficiently by adjusting the heating or cooling output according to the outdoor conditions.
Because it absorbers the heat
The heat emanated from the streets, as it was 90 degrees outside.
yes you can
About 10% during the outdoor temperature from about 40 degrees to 20 degrees. Not a lot beyond those temperatures that make frost on the outdoor coil...assuming you have a unit with a good electronic defrost control.
A heat exchanger in a house works by transferring heat between indoor and outdoor air. It does this by using a system of pipes or coils to pass the air through a heat transfer medium, such as water or refrigerant. As the indoor air passes through the heat exchanger, it releases heat to the medium, which then carries it outside. At the same time, the outdoor air passing through the heat exchanger absorbs the heat from the medium and brings it inside. This process helps to efficiently regulate the temperature in the house by exchanging heat between the indoor and outdoor air.
A heat pump generally has a max temperature change of 20 degrees F. If air entering the return duct is 90, it will not be cooler than 70 on the discharge side, Below 60, it is working against the insulation and air infiltration into the house. It is an air conditioner, not a deep freeze. Remember that a heat pump either dumps heat outside to cool a house, or picks up heat from outside to heat the house. If it is 100 degrees outside, it is hard to dump heat. Below 35, it is hard to pick up heat. At an outside temp of 59 degrees, it should work for either- but nobody needs cooling when it is 59 degrees outside. Open a window, already!.
Normally it would be 32 degrees without a heat strip installed.
With heat pumps supply air temp will vary with outdoor temp. The colder it gets outside the less efficient the heat pump will be (colder supply air).
Your house may be hotter than outside because of factors such as insulation, sunlight exposure, and heat generated by appliances and people inside. These factors can trap heat indoors and make it feel warmer than the outdoor temperature.
It is possible that the outside temperature sensor is defective. As a result the heat only works at certain electronic temperature control settings.
