A heat dissipation device for electronic device, a heat dissipation assembly, an air pipe assembly and a table. The heat dissipation device includes a refrigerator, an air pipe assembly and a heat dissipation assembly. The refrigerator has a cool air opening. The air pipe assembly has a first and second end portions, the first end portion detachably connects to the cool air opening. The heat dissipation assembly has a base body detachably connected to the refrigerator and a supporting plate pivoted to the base body. When the supporting plate is in a first position, the supporting plate has a first angle with a bottom plate of the base body. When the supporting plate is in a second position, the supporting plate has a second angle with the bottom plate. The second end portion is detachably connected to the supporting plate and is movably disposed in the air permeable.

An air conditioning unit includes a compressor, a condenser coil, a condenser outdoor fan, a metering/expansion device, an evaporator coil and an evaporator/indoor fan. The outdoor fan and the indoor fan are direct drive plenum fans controlled by variable frequency drives.

An air conditioner having six ports is described. The inner space of a casing having six inlet/outlets including a first discharge port, a second discharge port, a first outdoor air intake port, a second outdoor air intake port, and an interior air suction port is divided by a partition wall to form a first passage and a second passage. A waste heat recovery heat exchanger is provided between the first passage and the second passage. The air flow direction and the air volume can be controlled by using a direction change damper, a first air volume control damper, and a second air volume control damper.

A portable environment control system is configured to condition the air within an enclosure, such as by heating, cooling, humidifying or dehumidifying. The portable environmental control system has a conduit that is attached at one end to an environment control device and attached at the opposing outlet end to a partition coupling. The partition coupling is configured over an opening in a partition, such as an exterior wall of a recreation vehicle. Airflow from the environment control device is configured to flow through the conduit and through the partition coupling to an enclosure. The portable environment control system is quick and easy to install and allows for closure of an opening in a partition with a flange cover. The portable environment control system may have an inlet and outlet conduit to provide air flow to and draw air flow from an enclosure, respectively.

A heat pump apparatus module for heating and/or cooling supply water, the heat pump apparatus module including: an apparatus housing at least partly provided with an outer wall; a heat pump arrangement including a condenser, an evaporator, and a compressor arranged between said condenser and said evaporator, said compressor configured to transfer a heat transferring medium from said evaporator to said condenser; wherein said heat pump apparatus module is divided into at least two separate compartments being: an air-flow compartment including a first heat pump component being either the condenser or the evaporator, and being configured to allow air to flow through said air-flow compartment, said first heat pump component configured to utilize said air for heating or cooling said heat transferring medium; a first closeable compartment being accessible through a first closeable opening.

When a humidity condition, including a humidity detected by a temperature and humidity sensor and a humidification load sensing unit falling below a threshold value, is met, an outside air conditioner supplies the heated and humidified air into the room. When the humidity condition is met during the indoor heating operation, the indoor heating operation is stopped or weakened. When the humidity condition is met, only the outside air conditioner is subjected to a heating and humidifying operation. Since the indoor air is not heated by the inside air conditioner more than necessary, when a heating load is low and a humidification load is present, a “conflicting state” can be prevented in which the inside air conditioner is subjected to a cooling and dehumidifying operation and the outside air conditioner is subjected to the heating and humidifying operation.
