Air source heat pump is a new type of efficient and energy-saving heating equipment. It uses air as the heat source to convert the external low temperature heat energy into high temperature heat energy to realize indoor heating. In coal mine heating, air source heat pump has the following applications:
Heating of underground ventilation system of coal mine: the underground ventilation system of coal mine needs to continuously discharge exhaust gas to the ground, and these exhaust gases contain a lot of heat energy, which can be recycled and heated by air source heat pump, thus realizing the heating and energy recovery of underground ventilation system of coal mine.
Heating of office and workshop in coal mine: indoor space such as office and workshop in coal mine also needs heating. The traditional heating method generally uses coal-fired boilers, which pollutes the environment. The air source heat pump can effectively reduce the consumption of coal resources and environmental pollution by using environmental protection and energy-saving heating.
Heating and hot water production in coal mine living areas: heating and hot water are also required in coal mine living areas, such as staff dormitory, canteen and other places. The use of air source heat pump for heating and hot water can reduce the dependence on coal, and also improve the comfort of employees' life and work.
The waste heat recovery heat pump module unit of Kcalin mine exhaust air can recover the waste heat of the mine exhaust wellhead, the water source heat pump unit can recover the waste heat of the mine water inrush, and the waste heat of the compressed air fan can be recovered by the waste heat recovery unit of the compressed air fan. The unit is easy to install and use, and the heat after heat recovery can be used for domestic water, building heating, wellhead antifreeze, etc.
In general, the application of air source heat pump in coal mine heating can effectively solve the problems of coal resource consumption and environmental pollution, and also improve the comfort of coal mine work and life.
