Heat pump technology is a new energy technology that has attracted much attention worldwide in recent years. For example, a water pump mainly pumps water from a low position to a high position, while an air source heat pump hot air machine can obtain low-grade heat energy from the air in nature. After the compressor is powered on to do work, it provides high-grade heat energy that can be used by people. It is used in the field of heating and has high thermal efficiency. It can replace heating by fuel oil, gas, coal-fired boilers, electric heating pipes and steam, thereby saving a lot of primary energy, and has very good energy-saving and environmental protection effects.

[0003] In traditional air source heat pump hot air blower, the evaporator is inside the chassis and can only absorb energy from the air. The energy absorption source is relatively single. In addition, since the inside of the chassis is relatively closed, the air flow is relatively poor, resulting in low energy absorption efficiency of the air source heat pump. In order to solve the above problems, an adjustable air source heat pump hot air blower is proposed. Utility Model Content
