According to some embodiments, a hermetically sealed container may have sides defining an interior portion that is able to hold gas at high pressure, such as at least substantially 2 times standard atmospheric pressure. One or more data center computer servers may be located within the interior portion and the high pressure may improve heat transfer for a data center. At least one side of the container may include a hermetically sealed electrical and/or optical feed-through providing an ability to connect the computer server to an element outside of the interior portion (e.g., a power source and/or another data center computer server) and a mechanism to remove heat from the container, such as a liquid loop heat exchanger, etc.

A central air-conditioning system, comprises a plurality of air-conditioning assemblies (1) and a plurality of range hood assemblies (2); each air-conditioning assembly (1) comprises a compressor (11), a first heat exchanger (12) and a second heat exchanger (13) which are connected with each other through refrigerating medium pipes (14); all the range hood assemblies (2) are in communication with the public flue (6); a third heat exchanger (3) and the second heat exchanger (13) is connected through a secondary refrigerant channel (4); each end of each secondary refrigerant channel (4) respectively exchanges heat with the second heat exchanger (13) and the third heat exchanger (3). As all the range hood assemblies (2) are in communication with the public flue (6), the third heat exchanger (3) exchanges heat with the second heat exchangers (13) through the secondary refrigerant channel (4), when the system is operating, the heat energy generated by the air-conditioning assemblies (1) can be discharged through the public flue (6).

An air-source heat pump air conditioner includes a first heat pump including a first refrigeration cycle that is formed by a first air-conditioning heat exchanger, a first heat-source heat exchanger, a first compressor, and first refrigerant flowing therethrough; a second heat pump including a second refrigeration cycle that is formed by a second air-conditioning heat exchanger, a second heat-source heat exchanger, a second compressor, and second refrigerant flowing therethrough; and an air conditioner control device configured to control the first heat pump and the second heat pump to operate at least one of the first refrigeration cycle and the second refrigeration cycle for a space to be air conditioned, the air-conditioning air containing outside air, return air, and other air that exchange heat with the first circulating refrigerant and the second circulating refrigerant in the first air-conditioning heat exchanger and the second air-conditioning heat exchanger.

Systems and methods for modulation of airflow within an existing air conditioning system are described. The existing system includes an air conditioning or HVAC unit coupled with air supply and return ducts. Motorized dampers can be controlled by a controller that receives information about various rooms and areas from temperature and occupancy sensors within those rooms or areas. In this manner, conditioned air can be directed to those rooms that are occupied and whose temperature needs correction based on a thermostat setting.

A duct type air conditioning system includes an air conditioner; a plurality of ducts that are disposed in a plurality of air-conditioned spaces that are supplied with conditioned air of the air conditioner; a plurality of room temperature sensors that are disposed in the air-conditioned spaces; a control device that controls the air conditioner; and controllers that control the air conditioner. The control device determines a room temperature sensor disposed in any of the air-conditioned spaces on which an air-conditioning starting operation is performed by the controllers by using sensor setting information in which the air-conditioned spaces and the room temperature sensors are associated with each other. The air conditioner includes an air-conditioning control degree calculating unit that calculates a degree of control of the air conditioner on the basis of a room temperature detected by the room temperature sensor determined by the control device.

A method for air conditioning including installing an air conditioning unit at a desired location. The air conditioning unit includes a housing that has air supply inlets and exhaust air outlets. The housing encloses a mode control unit that switches a zone coil associated with a zone from a cooling mode to a heating mode by switching from a cooling medium to a heating medium flowing through the zone coil. The zone coil receives the heating or cooling medium and conditions incoming air from a supply fan to be exhausted in a zone associated with the zone coil. A variable refrigerant flow cooling/heating unit provides a cooling medium or a heating medium at varying rates to control a temperature of a zone.
