The outdoor coil is a condenser in the cooling mode and an evaporator in the heating mode.. (pg. 1077) -MAS
It is preferable to locate the OD unit above the ID unit to ensure that the oil does not accumulate in the evaporator over a period of time.
An indoor unit is not called an evaporator because the term "evaporator" specifically refers to a component within the air conditioning system that is responsible for absorbing heat from the indoor air and converting liquid refrigerant into a gas state. While the indoor unit may contain the evaporator coil, it encompasses other components like the blower fan and air filter that work together to distribute conditioned air throughout the space.
Split heat may refer to a heating system that utilizes a heat pump with two main components - an indoor unit (evaporator) and an outdoor unit (condenser). The indoor unit absorbs heat from the ambient air, while the outdoor unit releases that heat into the surrounding environment. This setup allows for efficient heating and cooling of a space.
Do you perhaps mean the 'lineset'? If so, it is usually a copper line (actually 2 copper lines) running counter-currently. They connect the indoor evaporator coil (above furnace or air-handler) to the outdoor condenser. One tubing carries the refrigerant gas from the indoor evaporator coil to the outdoor condenser and the other line carries the condensed (liquid) form of this gas back to the evaporator coil for it to be evaporated again and be converted back to gas. This is the refrigeration cycle of an A/C unit.
In a heat pump system, the indoor unit is not called the evaporator because it serves a dual function as both the evaporator (during cooling mode) and the condenser (during heating mode). The indoor unit absorbs heat from the indoor air during heating mode and releases it into the indoor space, while it absorbs heat from the indoor space during cooling mode and releases it outside.
The coil that serves the inside of the house is called the indoor coil. The reason is that the indoor coil is a condenser in the heating mode and an evaporator in the cooling mode.. (pg. 1077)
why is it important to have drainage for the outdoor unit
why is it important to have drainage for the outdoor unit
Refrigerant is pumped by a compressor located in the out door section called the condensor to a evaporator coil as a liquid through a metering device.Your air handler or furnace blows air from your home across the evaporator where the liquid refrigerant expands into a gas and picks up the heat from the air across the coil.Then the gas is pumped to the condensor and is again condensed into a liquid through the means of cooling the gas usually by a fan pulling air across the coils of the outdoor unit.
Low Ambient Temperature.The mechanical refrigeration system used in air conditioning equipment is design to work when the outdoor temperature is above 65°F. If the AC runs when the temperature is too low will cause the evaporator coil to drop in temperature and freeze over. BigBOB
The 41 indicates 41,000 Btus/hr. There are 12,000 in a ton. You have a 3.5 ton coil, but that number will vary according to how it's matched to the outdoor unit.
