Abstract

The invention provides a liquid dehumidifying multifunctional air source heat pump system and a running method thereof. The system comprises an air source heat pump subsystem which consists of a compressor, an evaporator, a condenser and a throttle mechanism. The system is characterized in that the multifunctional air source heat pump system is also provided with a solution dehumidifying subsystem which is used for dehumidifying the air and then transmitting the air into the evaporator. In the method, before entering the evaporator, the air is treated by dehumidifying. The invention can solve the problems that an outdoor fin heat exchanger is seriously frosted when the heat pump in the winter, and the efficiency is reduced. Furthermore, low-grade heat source is fully used, and the room can be humidified and heated when the dehumidifying solution is regenerated.

Description

Technical field [0001] The invention relates to a frost-proof multifunctional air source heat pump system, which uses a solution dehumidifier for regeneration of a low-grade heat source to dehumidify the air, and further realizes the anti-frost heating of the air source heat pump in winter, indoor humidification and energy-saving treatment of heat and humidity in summer A multifunctional air conditioning equipment and a new method of air treatment in operation, specifically an energy-saving device that combines renewable energy technology, solution dehumidification technology, and heat pump technology. Background technique [0002] In my country, with the continuous rapid development of the construction industry, building energy consumption has accounted for 20% to 25% of the country's total energy consumption. This part of the energy consumption has an important impact on greenhouse gas emissions. In building energy consumption, heating and air conditioning energy consumption ac...
