Open-loop lithium bromide heat pump system

Abstract

The invention relates to the system of heat pumps and discloses an open-loop lithium bromide heat pump system. The open-loop lithium bromide heat pump system comprises an evaporation chamber, an absorption chamber and a generation chamber. Steam in the evaporation chamber is transported into the absorption chamber through a first pipeline by the evaporation chamber. Diluted lithium bromide in theabsorption chamber is transported into the generation chamber through a second pipeline by the absorption chamber. Concentrated lithium bromide in the generation chamber is transported into the absorption chamber through a third pipeline by the generation chamber. A refrigerant water tank communicates with the evaporation chamber through a fourth pipeline. A first heat exchange pipe is coiled in the generation chamber. After heat exchange is conducted on high-temperature steam in the first heat exchange pipe and the diluted lithium bromide in the generation chamber, the high-temperature steamflow out of the generation chamber. A fifth pipeline is mounted in the generation chamber, wherein the fifth pipeline is used for transporting secondary steam to equipment using heat. A vacuum degassing tank is mounted on the fourth pipeline, wherein the vacuum degassing tank is used for taking air off water. According to the open-loop lithium bromide heat pump system, refrigerant water is in an open loop and a non-circulating system; therefore, the amount of water absorbed from the evaporation chamber by the heat pump is equal to that of steam produced from the generation chamber; and refrigerating capacity is acquired by an user, and meanwhile, high-temperature steam with utility value can be acquired.

Description

technical field [0001] The invention relates to a heat pump system, in particular to an open-loop lithium bromide heat pump system. Background technique [0002] The refrigerant water of the existing lithium bromide heat pump is evaporated in the evaporation chamber, and the steam generated enters the absorption chamber, and is absorbed by lithium bromide in the absorption chamber, and the lithium bromide that has absorbed the water vapor is sent to the generation chamber for evaporation, generating secondary steam, which enters condensation The chamber is condensed into water, and then enters the evaporation chamber for recycling. At this time, the temperature of the secondary steam generated in the generation chamber is relatively high, which is useful. However, the existing technology does not use this heat, but is emptied by the cooling tower through the condenser. This not only wastes the thermal energy of the valuable secondary steam, but also greatly increases the bur...
