Cleaning unit and absorption water chiller and heater employing the same

Abstract

The invention relates to a cleaning unit for an absorption water chiller and heater. The cleaning unit comprises an absorption liquid inlet pipe, a nozzle arranged at an end portion of the absorption liquid inlet pipe for spraying absorption liquid, a cleaning pot for storing absorption liquid sprayed by the nozzle, wherein the cleaning pot communicates with the absorption liquid inlet pipe, a gas distribution pipe communicating with the cleaning pot so as to place the end of the distribution pipe at a place near the nozzle and to allow the useless gas in the water chiller and heater flowing into the gas distribution pipe, and apertures arranged on the gas distribution pipe. If the diameter of the nozzle is d(mm), the diameter of the apertures is D (mm), temperature in the cleaning pot is T (Deg C), and the inner pressure of the cleaning pot is P (Pa), the following formula can be satisfied: 0.001<(d2+(1+D) / P3) / (D2-(2 / T)2)<0.01.

Description

technical field [0001] The present invention relates to an absorption chiller and hot water machine, in particular to a purge unit for discharging non-condensable gas inside the absorption chiller and hot water machine to the outside. Background technique [0002] The absorption chiller is a system that uses the vapor absorption characteristics of lithium bromide (LiBr) aqueous solution to realize cooling and heating. In order to ensure its performance, the interior of the chiller is kept in a high vacuum state. In addition, the absorption cold and hot water machine is different from the cold and hot water machine that uses electricity as an energy source. It uses gas such as LPG and LNG as a heat source, thereby solving the excessive power load in summer and having waste heat. Various advantages such as the full utilization of the thermal combination system. [0003] figure 1 It is a schematic diagram showing an ordinary absorption type cold and hot water machine. [000...

AI Technical Summary

Problems solved by technology

[0011] However, in the conventional absorption chiller 1, there is a problem that the cooling capacity is reduced due to the generation of non-condensable gas inside the chiller.

In the past, a device for discharging non-condensable gas has also been developed, but in this device, not only the non-condensable gas is discharged, but also the water vapor inside the hot and cold water machine is also discharged, which will cause the cold and hot water machine to Many problems occur at work
