Description

This application claims priority to US Provisional Patent Application No. 61 / 546,271, filed Oct. 12, 2011, which is incorporated herein by reference for all purposes. To do.

  Conventional indoor air conditioners use state change technology to dehumidify the air. This dehumidification can be a problem on very humid days as the device overflows from water extracted from the air. This overflow can be as much as 1 liter depending on the condition of the day.

  There is currently a need for a more effective and environmentally friendly air conditioning system. These improved systems can be based on water or emulsion loops to transport exhaust heat outside the building.

  Embodiments described herein provide a room cooling system that can be installed by a user. This system is cost effective to produce in large or small size and uses little electricity compared to conventional compression cycle air conditioning systems currently available.

  The disclosed invention can operate from a line or can operate from a low voltage DC, such as 48 volts. This system does not require a drain for condensate but can be used as a dehumidifier if a drain is connected. Alternatively, the system can be adjusted to have a net zero effect on humidity.

  These and other aspects of the disclosed subject matter as well as additional novel features will become apparent from the description provided herein. The purpose of this summary is not a comprehensive description of the claimed subject matter, but rather provides a short overview of some of the subject matter's functionality. Other systems, methods, features and advantages provided herein will become apparent to those skilled in the art with reference to the following drawings and detailed description.

  The invention itself, and preferred methods of use, further objects and advantages thereof, are best understood by reference to the following detailed description of the illustrated embodiments when read in conjunction with the accompanying drawings.

It is a system diagram of an embodiment of the present invention.

  The disclosed embodiments describe a cost and energy efficient indoor system. This system can utilize a flexible distributed air handler that can use a distributed heat exchanger for the liquid loop. The liquid loop may only require a single loop, maintaining the low pressure in the loop and achieving higher efficiency when evaporative cooling tower technology is utilized.

  The disclosed system works in an effectively insulated room with little heat loss. Exemplary embodiments include a heat to air transfer plate 1, a heat pump 2, a block of heat transfer material 3, a pump 5, a pipe interface 6, a temperature control system 8, an outer radiator or evaporative cooling. Can be constructed from the vessel 7 and is filled at the highest point.

  The heat and air moving plate 1 may have an attractive shape and may have a surface area sufficient to heat or cool the amount of air in the space. The heat pump 2 may be a Peltier element or a magnetocaloric element and acts to transport heat from or to the heat and air moving plate 1.

  The block 3 of thermally conductive material may be any suitable material that can transfer heat between the surfaces from the heat pump 2 to the liquid medium. This material can be composed of, for example, aluminum or copper.

  The pump 5 may be utilized to circulate a liquid such as water through the block 3 of heat conductive material and the outer radiator 7. The pipe interface 6 may extend from the block 3 of thermally conductive material to the outer radiator 7.

  The temperature control system 8 can be used to protect Peltier elements and to manage optimal performance based on room and external temperatures. The temperature control system 8 can also operate freezing control.

  When the disclosed system is cooled, condensate may form on the heat and air moving plate 1. Due to the force of gravity, the condensate flows down to the plate 1 in the recovery area and drops into the recovery area on the block 3 of heat transfer material that transfers heat from the elements of the heat pump 2 to the liquid medium. This system is deliberately controlled to operate at an exhaust temperature of at least 100 ° C., and water dripping onto the block 3 of heat transfer material evaporates fairly quickly. The evaporation of the condensate gives a net zero result for room humidity.

  Humidity can be controlled by lowering the exhaust temperature with the electronics of the control system 8. This control can delay the evaporation process and increase the amount of condensed water in the recovery zone. In one embodiment, the pump, which may be the same as the pump 5 used to circulate water or other liquid, detects this increase in condensate and either out of the building or in a particular condensate exhaust pipe Excess water can be pumped out and the pump can transport this water to a water evaporative cooling tower or other processing equipment.

  The control system 8 and the power supply can provide 48 volt bus power for the heat pump 2. The heat pump 2 may be 300, 400 or 1000 watts for a single device, but different wattages may be utilized, and are within the scope of this disclosure. The control system 8 manages the pump and returns or raises the water temperature and plate dew point temperature.

  The present invention is well adapted to achieve the end objectives and advantages described herein. The specific embodiments described above are exemplary only, and the invention may be modified and implemented in different but equivalent ways that will be apparent to those skilled in the art from the teachings herein. Furthermore, it is not intended to be limited to the details of construction or design herein shown, other than as described in the appended claims. Accordingly, the particular exemplary embodiments described above may be altered or modified and all such variations are considered within the scope and spirit of the invention. Also, the terms in the claims have their clear ordinary meaning unless otherwise clearly and expressly defined by the patent owner.
