What Does a Zuba Central Heat Pump Do?

A heat pump does two things and employs the same basic principles for both. The system consists of an outdoor unit and an indoor unit, with two small refrigerant pipes connecting them. Working like an air conditioner on warm days, the pump will extract heat from inside the home and transfer it outdoors. On cold days the pump will extract heat from the outside air and transfer it inside.

Traditionally, heat pumps do not perform well when outdoor temperatures drop below 0°C, even though there is still heat energy in the frigid air. These heat pumps need to be matched with a supplementary heating method, normally a gas-fired furnace. Since both heat pump and gas furnace cannot operate at the same time, it usually means that you are not getting any benefits from your heat pump in the middle of the winter.

The Zuba-Central heat pump performs well at temperatures as low as -30°C and below. Even in those rare instances when extreme temperature hits the air, Zuba-Central can be equipped with auxiliary heaters. Zuba-Central is ideal for homes in any part of Canada.

How Does the Zuba Central Heat Pump Work?

Summer, Winter Cycles
  1. A refrigerant coil is located inside the indoor air handling unit.
  2. Warm indoor air from the return air duct passes through the coil which is filled with cold liquid refrigerant.
  3. The refrigerant absorbs heat energy from the air and evaporates into warmer gas form, while the now chilled air is delivered back into the house.
  4. The warm gas refrigerant then gets pumped into the compressor located in the outdoor unit which prepares it into a high-pressure, high-temperature state before moving onto the coil in the outdoor unit.
  5. Now the temperature of the refrigerant is much higher than the outdoor air. As the outdoor fan blows cooler air across the coil, it also picks up heat energy from the refrigerant, which then condenses into cold liquid form again before transferring to the indoor unit. And the cycle continues.

In heating mode, a heat pump may be thought of as an air conditioner equipped with a reverse mode.
