高いものではなかつた。 In general, absorption heat pumps connect a generator, condenser, evaporator, and absorber with airtight piping to form a circulation cycle of refrigerant and absorption liquid. The heat obtained is supplied to the outside of the machine from the absorber and/or condenser. However, not all of the heat given to the generator for this kind of heat pump operation (hereinafter referred to as driving heat) is used as a heating source and cannot be supplied outside the machine, and this driving heat absorbs refrigerant. Heat pump operation efficiency was not high because it was mainly used to heat the liquid to re-separate the refrigerant from the absorption liquid (hereinafter referred to as concentrated liquid) with a high concentration of refrigerant.

By doing so, the purpose is to improve the airtightness of the machine, reduce the loss of driving heat, and improve the thermal efficiency of the heat pump.

This is a demultiplexer that performs the final separation of the demultiplexer 4.
The separated and liquefied liquid is led to a liquid dispersion device 6, where it is dispersed from the upper part of the rectifier 3 and used as part of the gas-liquid contact liquid for separating the refrigerant and the absorbent. Also, 7 is an air heat exchange type evaporator, 8
The refrigerant is separated in the generator 1 and an absorption liquid (hereinafter referred to as diluted liquid) with a low refrigerant concentration is dispersed to absorb the refrigerant gas vaporized in the evaporator 7, whereby the evaporator 7 reaches a low temperature level. For example, the absorber pump 9 is an absorbent pump that returns the concentrated liquid that has absorbed the refrigerant in the absorber 8 to the generator 1. A cooler 11 for cooling the inside of the demultiplexer 4 and a heat exchanger 12 for preheating the concentrated liquid by exchanging heat with the diluted liquid sent from the generator 1 to the absorber 8 are arranged in the concentrated liquid pipe line 10. It is set up.

Together with the concentrated liquid sprayed on the air, it flows down the collection section 18 and returns to the generator 1.

率の向上にとつて効果の大きいものである。 In the absorption heat pump of the present invention, the high temperature level from the rectifier is reduced by arranging the absorber so as to circulate around the recovery section of the rectifier, which has the second highest temperature level next to the generator in the machine. It is possible to reduce the heat dissipation loss of the machine, as well as to recover heat by the condenser placed around the top of the rectifier, and to reduce the machine surface area per unit refrigeration capacity. This is highly effective in improving the operating efficiency of heat pump machines that supply heat while minimizing heat leakage.

ある。 In addition, since the absorber and condenser are coil-type heat exchangers that go around the rectifier, long tubes can be used as they are as heat exchangers, instead of welding short tubes as in the past. Compared to a structure in which the heat exchanger is formed using a heat exchanger, the width of the welding area for machine manufacturing can be reduced and the manufacturing process can be simplified. In addition, unlike conventional absorption heat pumps, the space occupied is large, and the arrangement of an independent rectifier imposes restrictions on the arrangement of other heat exchanger groups. It is possible to provide an absorption heat pump having a structure that eliminates the above disadvantages and is suitable for adoption of automated welding or automated assembly.
