A heating and cooling system includes a heat exchange section to transfer heat between refrigerant and air in both a heating mode and a cooling mode. The heat exchange section includes at least two refrigerant passes. Refrigerant is circuited through the refrigerant passes in the same direction in both the heating mode and the cooling mode, so that the overall flow orientation between the refrigerant passes and the air is a counter-flow orientation in both the heating mode and the cooling mode.

Heating and cooling unit

An evaporator includes an inlet manifold, an outlet parallel to the inlet manifold, and a collection manifold parallel and adjacent to the outlet manifold. First flow conduits extend from the inlet manifold to the collection manifold, and at least one second flow conduit extends from the collection manifold to the outlet manifold. The evaporator can be housed within an enclosure to provide a cased evaporator. Air is conditioned by transferring heat from the air to refrigerant as the air passes through the evaporator. The refrigerant is received from outside the enclosure into the inlet manifold, and is directed through first and second refrigerant passes to receive heat from the air. The flow of refrigerant is received from the second pass into a collection manifold, is transferred to an outlet manifold, and is removed from the enclosure.

Heat exchanger

A heat exchanger including a tube having inlet ends and outlet ends and defining a flow path therebetween. The tube can have a first section and a second section arranged at an angle with respect to the first section. Each of the first section and the second section can include a first subsection and a second subsection arranged at an angle with respect to the first subsection.
