Basement temperature and humidity system and control method thereof

Abstract

The invention relates to the technical field of air conditioning systems, in particular to a basement temperature and humidity system which comprises a cooling and heating system, an air processing system and a control system.The cooling and heating system comprises a heat pump host, an air conditioning system water supply pipe, a fan coil, an air disc electric water valve, a water segregator, a ground coil, a water return switch valve, an air conditioning system water return pipe and a water pump; and the air processing system comprises a variable-temperature fresh air dehumidifier outdoor unit, a variable-temperature fresh air dehumidifier indoor unit, a refrigerant pipeline, an air supply pipeline, an indoor air supply outlet, an indoor air return inlet, an air return pipeline and a fresh air pipeline. The system has the advantages of being simple in structure, convenient to regulate and control, stable in operation and low in manufacturing cost, and the control method has the advantages of being clear in target, digital in monitoring, capable of automatically operating all the year round, safe, reliable and the like.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to an underground room temperature and humidity system and a control method thereof. Background technique [0002] The above-ground air-conditioning system is used in the basement. The humidity in the basement is often poorly controlled and the problem of mold and condensation still occurs. The temperature and humidity conditions in the basement are different from those on the ground, and different temperature and humidity systems and control methods are required. For the existing Propose a new solution to the problem. The problems existing in the existing air-conditioning system and its control in the basement mainly include: [0003] 1) Adopt the same scheme as the ground; [0004] 2) Using relative humidity control, there are more problems at low temperature; [0005] 3) The operation mode needs to be set manually, and there is no automatic operation; [0006]...
