[0015] 1. The waste gas is transported to the interior of the heat pump main body through the flue conveying pipe, and the high-temperature gas transported in is absorbed by the fin evaporator. When the high-temperature gas passes through the fin evaporator, the refrigerant inside the fin evaporator absorbs the heat in the air and evaporates into a gas. At this time, the low-pressure gas is sucked into the compressor, and the pressure and temperature of the refrigerant are increased by the compressor. The high-temperature and high-pressure refrigerant then passes through the heat exchanger, transferring the heat to the liquid inside the liquid storage tank, raising its temperature and transporting it to the interior of the boiler main body. High-temperature steam is produced by heating through the steam generator. The high-temperature and high-pressure coolant then passes through the expansion valve, reducing its pressure and temperature simultaneously. The low-temperature and low-pressure coolant after passing through the expansion valve absorbs heat and evaporates through the fin evaporator, thereby lowering the air temperature inside the fin evaporator, and the coolant returns to the low-pressure state again. The heat pump boiler unit can collect the waste heat in the discharged medium and low-temperature waste water and waste gas and convert it into high-temperature steam at about 120°C.

[0016] 2. This application not only helps to reduce energy consumption, but also can effectively reduce environmental pollution and achieve sustainable development. It has a wide range of applications and can be used in industrial production (a large amount of thermal energy is discharged into the environment in the form of waste gas, waste water, etc.), the construction field (condensate water discharged by air conditioners, hot air discharged during heat dissipation), the agricultural field (in greenhouse cultivation, by recovering and utilizing the waste heat in the greenhouse), etc. It has low noise, recovers waste gas and waste water, reduces environmental pollution, has relatively low operating costs, and is stable.
