The present disclosure relates to air conditioning systems and methods. An aspect of the present disclosure is a device that includes a housing having an external surface and defining an interior volume, a heat exchanger positioned within the interior volume, a fluid line partially positioned within the interior volume, a sleeve extending from the external surface and terminating at a distal end of the sleeve, and a fluid connector. The sleeve has an outside wall spanning a length of the sleeve and defining an internal cavity, the fluid connector is positioned at or near the distal end, a portion of the fluid line is positioned within the internal cavity, and the fluid line provides a fluid connection between the heat exchanger and the fluid connector.

A combination of high efficiency ductless air conditioners and heat pumps installed in a window opening. A metal frame, mounted over the sill like a bridge, structurally links an indoor unit and outdoor unit. Flexible tubing inside the frame operationally connects the units. The outdoor unit is flexibly connected to the frame so it can be flipped 90 degrees from a horizontal position to a downward vertical position and vice versa. Thereby the length of the outdoor unit is not limited by the dimensions of the window opening. Hence the outdoor unit can have a large condenser and coils with large surface to achieve high efficiency. The indoor unit is slidably connected to the frame so it can be slided towards or away from the outdoor unit. The frame is secured to the window opening via a security bar. The indoor unit further enhances efficiency through 3-side air return.

A refrigeration device has a condenser coil that has periodic access to outside air. A time-activated thermostat controls the operation of an evaporator coil that is in thermal contact with a reservoir containing phase change material. A thermally conductive pipe containing antifreeze fluid is connected to a pump that circulates the antifreeze fluid inside the pipe. A first portion of the pipe is inside the reservoir in thermal contact with the phase change material and a second portion of the pipe is near an air fan or connected to a fan coil unit to exchange heat through the pipe between the reservoir and the air blown by the fan or the fan coil unit. The evaporator coil produces a phase change in the phase-changing material in the reservoir at night when outdoor temperature is colder than during day and the phase-change material is used during day to cool air blown by the air fan or the fan coil unit. The air fan and a portion of the pipe can be outside of the refrigeration device and be detached.

A rubber body as an elastic body for closure closes a gap between a partition plate in which a through-hole is formed and refrigeration piping inserted through the through-hole. The rubber body for closure includes a pressurized insertion receiving portion having formed therein an opening into which the refrigeration piping is pressed and inserted, the pressurized insertion receiving portion elastically pressing and contacting in a liquid-tight manner an external surface of the refrigeration piping; a fitting portion fitted in a liquid-tight manner the peripheral edge portion of the through-hole in a state in which an inner circumferential surface of the through-hole is elastically pressed; and a displacement allowance portion that closes a gap between the pressurized insertion receiving portion and the fitting portion, and to allow a relative displacement of the pressurized insertion receiving portion and the fitting portion in a direction parallel to the partition plate.

A window type air conditioner rack, having an upper frame main rack and a diagonal bracing rack inserted to the upper frame main rack; the diagonal bracing rack is adjustably fixed inside the upper frame main rack; the upper frame main rack has a windowsill connection assembly and horizontal supporting pillars fixedly mounted to the an outer side of the windowsill connection assembly.

A dehumidifier according to an aspect of the present disclosure includes: a body; and a water container mounted at an upper side of the body, wherein the body includes a seating part arranged at an upper side thereof and on which the water container is seated and a hollow connection port protruding upward from the seating part, and the water container includes a connection hole into which the connection port is inserted and a valve which opens the connection hole as the water container is mounted on the body. The dehumidifier prevents condensed water in the water container from leaking through the connection hole in a state in which the water container is separated from the body.
