Absorption heat pump

Abstract

The invention discloses an absorption heat pump which includes an absorber which uses the absorption heat which is generated when an absorption liquid absorbs steam of a coolant and generates a mixed fluid and also a gas-liquid separator (60). The gas-liquid separator (60) includes: a canister (61) is longer in the horizontal direction; a collision wall (63) which enables a mixed fluid (Wm) which flows from an inflow opening (61a) to the canister (61) to have collision; a detour forming road (65) which forms a detour which can increase the stroke of a fluid which collides with the collision wall (63) and reaches a outflow opening (61b), wherein the inflow opening (61a), the outflow opening (61b), and the collision wall (63) are formed at positions higher than a highest liquid level (WLH). The detour forming road (65) is configured to enable the fluid which has collided the collision wall (63) to circumvent the end part (65e) of the detour forming part (65) in the horizontal direction. A through flow path (68) for the fluid to go through is formed at the end part (65e) and between the detour forming part (65) and the canister (61).

Description

technical field [0001] The present invention relates to absorption heat pumps, and more particularly to absorption heat pumps with suppressed height. Background technique [0002] There is a second type of absorption heat pump as a heat source machine that takes in a heated medium whose temperature is higher than that of a driving heat source. The second type of absorption heat pump has, as its main structure, an evaporator that evaporates the refrigerant liquid, an absorber that absorbs the refrigerant vapor with the absorption liquid, a regenerator that separates the refrigerant from the absorption liquid, and a condenser that condenses the refrigerant vapor. In the absorber, the heat generated when the absorption liquid absorbs the refrigerant vapor can be used to heat the liquid of the heated medium and evaporate it, and a gas-liquid separator is also provided, which introduces the heated heated medium and separates it into heated Medium steam and liquid. As such an ab...

Problems solved by technology

[0004] Since the absorption heat pump described in Patent Document 1 is arranged so that the gas phase part of the vertically long gas-liquid separator is at a higher position than the uppermost part of the main structure, the overall height of the absorption heat pump becomes too high, and due to the long The horizontal cross-sectional area of ​​the gas-liquid separator is relatively small, so the volume required for gas-liquid separation is ensured above the upper limit liquid level that should correspond to a relatively large liquid level change, so that the height is further increased, resulting in the setting conditions being restricted. restrict
