Air conditioner

Abstract

The air conditioner includes an air-conditioning core, a first air-conditioning passage, a liquid passage and a second air-conditioning passage. The core includes a Peltier device having first and second surfaces, a first surface-side passage and a second surface-side passage. The second surface-side passage has a first passage and a second passage that transfer heat therebetween. The first air-conditioning passage is connected to the first surface-side passage for allowing first air-conditioning air in the first air-conditioning passage to flow through the first surface-side passage. The liquid passage is connected to the first passage for allowing liquid that serves as a heat transfer medium to flow through the first passage. The second air-conditioning passage is connected to the second passage for allowing second air-conditioning air in the second air-conditioning passage to flow through the second passage. The first air-conditioning air and the second air-conditioning air are usable for air conditioning a room.

1 . An air conditioner comprising:
 an air-conditioning core comprising:
 a Peltier device having a first surface and a second surface one of which serves as a heat absorbing surface and the other of which serves as a heat radiating surface; 
 a first surface-side passage located adjacent to the first surface of the Peltier device; and 
 a second surface-side passage located adjacent to the second surface of the Peltier device, the second surface-side passage having a first passage and a second passage that transfer heat therebetween; 
   a first air-conditioning passage connected to the first surface-side passage for allowing first air-conditioning air in the first air-conditioning passage to flow through the first surface-side passage, wherein the first air-conditioning air is usable for air conditioning a room;   a liquid passage connected to the first passage for allowing liquid that serves as a heat transfer medium to flow through the first passage; and   a second air-conditioning passage connected to the second passage for allowing second air-conditioning air in the second air-conditioning passage to flow through the second passage, wherein the second air-conditioning air is usable for air conditioning the room.   
     
     
         2 . The air conditioner according to  claim 1 , wherein the first passage is opened to the atmosphere via a relief valve. 
     
     
         3 . The air conditioner according to  claim 1 , wherein the second passage has a valve that is operable to open and close the second passage. 
     
     
         4 . The air conditioner according to  claim 1 , wherein the Peltier device, the first passage and the second passage are disposed in such superposed relation that the first passage is superposed on the second surface of the Peltier device and the second passage is superposed on the first passage. 
     
     
         5 . The air conditioner according to  claim 1 , wherein one of the first passage and the second passage has a right-side passage and a left-side passage and the other of the first passage and the second passage is held between the right-side passage and the left-side passage. 
     
     
         6 . The air conditioner according to  claim 1 , wherein the first surface-side passage has therein a first air-conditioning fin, the first passage has therein a heat source-side fin, and the second passage has therein a second air-conditioning fin.
