Abstract

A spray type air source absorption heat pump belongs to the technical field of heat supply. The spray type air source absorption heat pump includes a generator, an absorber, a condenser, a brine regeneration device, a spray tower, a solution heat exchanger, a solution pump and a throttle valve; the present invention adopts the existing centralized heating system Or directly burn fuel to drive an absorption heat pump, and extract low-grade heat energy from the air through a spray evaporator, which improves the primary energy efficiency of heating and reduces pollutant emissions. Compared with traditional air source heat pumps, there is no risk of frost in winter, which ensures the reliability of heating and reduces the area of ​​air-cooled heat exchangers. Using self-exhaust smoke or absorption heat pump refrigeration method can not only realize continuous regeneration of brine, reduce the amount of brine, but also greatly reduce the energy consumption of brine regeneration. The invention has obvious energy-saving and emission-reducing effects for heating supply and preparation of domestic hot water.

Description

technical field

[0001] The invention relates to a spray-type air-source absorption heat pump, which is used for heating and domestic hot water, and efficiently extracts heat from low-temperature air in winter, and continuously regenerates the refrigerant through its own smoke exhaust or absorption heat pump refrigeration. It is especially suitable for areas with low temperature in winter and belongs to the field of heating. Background technique

[0002] Building heating consumes a lot of energy in my country. From 1996 to 2008, heating energy consumption in northern cities and towns increased from 72 million tons of standard coal to 153 million tons of standard coal, accounting for 23% of the total energy consumption of buildings. With the rapid development of my country's cities and the continuous improvement of people's living standards, it will inevitably bring about the increase in the number of various energy-consuming equipment and the demand for service levels, and it...
