Air conditioning

 

The invention relates to techniques for air-conditioning based on the use of thermocouples with the Peltier effect. Air conditioning provides air ducts are air-conditioned and outdoor air located in each of the fan and thermoelectric modules with junctions. Working junctions of thermoelectric modules arranged in series along the flow on the surface of the working channel, and outside (utilizing) the junctions of each thermoelectric module is located in the duct for outside air parallel to each other. In addition, the working channel formed radiators facing edges to each other. The technical result is to increase the efficiency of thermopile and optimization of operation mode of the air conditioner. 2 Il.

The invention relates to techniques for air-conditioning based on the use of thermocouples with the Peltier effect.

Known air conditioning, containing the outer ducts and the conditioned air located in each of them with a fan and a thermopile with the seals installed in the ducts, and a polarity reversal switch. The duct air is exhaust and AHC attached to the flow regulator (Ed. mon. 779749, CL F 24 F 1/02, publ. 1980).

The disadvantage of this conditioning is the possibility of ice formation on the junctions, the removal of which requires special measures, such as creating an additional channel with the camera. It also creates unequal conditions of operation of the hot junctions of thermopile in the cooling mode due to the fact that the subsequent flow of hot junctions are cooled by air already heated to previous thread seals, which reduces the efficiency of thermopile and conditioning in General.

The invention is aimed at improving the efficiency of thermopile and optimization of operation mode of the air conditioner.

This is achieved by the fact that in conditioner containing ducts air and outdoor air located in each of the fan and thermoelectric modules with junctions, working junctions of thermoelectric modules arranged in series along the flow on the surface of the working channel, and outside (utilizing) the junctions of each thermoelectric module is located in the duct for outside air parallel to each other.

In addition, the working channel formed radiators facing edges to each other.

In Fig. 1 and ostujoud) 1 for the passage of conditioned (heated or cooled) air formed is made of material with good thermal conductivity, such as aluminum alloys, heat sinks 2 directed edges to each other. On opposite sides of the working channel is placed in series (chain) of thermoelectric modules (TEM) 3 facing the working junctions to the channel walls. On the outer side of thermoelectric modules 3 radiators 4 for diversion (recycling) in the atmosphere of heat (cold), released on the outside of the junction TEM during air conditioner operation. The radiator 4 is placed in the duct 5 to the air flow generated by the fan 6, with the possibility of blowing the fresh flow of outdoor air intake from outside the conditioned space, each of the heat sinks 4. To improve the efficiency of the air conditioner and prevent the flow of thermal energy working channel is placed in a heat insulating jacket 7. To supply air into the working channel 1 air conditioning is supplied by the fan 8, the ducts 9 and 10 to exhaust air from the conditioned space and the supply of fresh outdoor air, respectively, and a filter 11. For regulating the ratio of air and outdoor air are the gates 12 and 13 interconnected. At the output of RSOM.

Include a fan to provide air flow to the radiator to drain into the environment as heat (cold), released at the appropriate junction TEM, and apply power to thermoelectric modules. Then turn the fan 6 for supplying conditioned air into the working channel, the intake air passes through the ducts 9 and 10 respectively of conditionerremove premises and outside the premises. The ratio of air coming through the ducts 9 and 10, smoothly regulate by means of the valves 12 and 13 are connected to one another. The sucked air passes through the filter 11 and flows into the working channel. When the flow of air through the working channel (2 radiators and radiators 4 in thermoelectric modules maintain the required temperature between the hot and cold junctions. When this air flow in the working channel (duct air) sequentially exchanges energy with the working junctions of thermoelectric modules arranged in series on the working channel, and cooled (heated), and the junction of each TEM with utilizing hand (and in contact each with its own heat sink) is blown by the flow of outside air. The depth of cooling (heating) air ceteris paribus is changing the power settings TEM. Changing the operation mode for cooling air in the heating mode of air is realized by changing the polarity of the power supply thermoelectric modules.

Thus, the use of the conditioning will allow for a comparison with the prototype to improve the efficiency of thermoelectric modules and optimize the operation mode of the air conditioner due to more effective diversion (recycling) in the atmosphere of heat (cold), which becomes possible due to the fact that outside of the junction TEM placed parallel to the flow of outdoor air.
