Usually PTAC heat pumps are mounted on an outer window or wall, and they have a ventilation option that brings in outside air. Each ptac heat pump is controlled separately. Standard PTAC heat pumps comes in portable sizes which make them easy to replace without having to make structural alterations to the building or room in which they are situated.
How they work?
The heat pump includes an evaporator coil facing the space to be heated or cooled, and a condenser coil mounted to face the outside. Typically, PTACs have a two or three-speed fan within the room. The heating cycle on a PTAC uses a four way valve to turn around the flow of refrigerant, and some come with a supplementary heater for additional heat when the temperature dips actually low in the winter.
Older PTAC heat pumps include mechanical push buttons and mechanical controls for operation and fan control with a rotary knob to choose the temperature. However, as electronic controls have developed to the point that they are more lucrative, newer PTAC heat pumps add in remote control devices and even electronic touch pads. Newer units usually have energy saving features for instance sleep modes and other functions so that the temperature adjusts as per the amount of time that has elapsed. Choosing the capacity of a PTAC is quite easy. The rule of thumb is that the larger the BTUH of the unit should be in case square footage of a room is large. With PTAC heat pumps, drain piping is not needed. Any condensate water extracted out of the air by the evaporator coil is haggard onto the condenser coil surface by the condenser fan.
Benefits of PTAC heat pumps
- These pumps offer a number of benefits. These self-controlled systems can remove moisture and heat from indoor air quickly once the thermostat is set. You can use an automated fan setting or else you can select fan speed on your own. The identical basic settings such as fan speed and thermostat are used when heating is necessary.
- These heat pumps are easy to install because of their standard dimensions irrespective of the heating or cooling load requirements. And as both cooling and heating systems exist in a single unit, the installation is easier than if a split unit has been installed.
- In addition, unlike split systems that condition whole buildings via a system of ductwork, a PTAC only cools or heats the room in which it is installed. Thus, with numerous systems it is easy to control indoor temperature on a personalized, room by room basis.
- Contemporary PTAC heat pumps are also quiet and energy efficient. Also, airflow patterns are designed to lessen the amount of energy consumed by the fan. A competent PTAC system can result in operating savings in less than one year’s use.
Besides this, PTACs are quieter these days especially with acoustical rubber isolators under the compressor, isolated fan motors, and acoustically insulated bulkheads. Modern PTACs are perfect for use in dormitories, apartments, offices, institutional homes, and hotels.
