Indoor radiation cooling method and low-temperature radiation panel split air conditioner

Abstract

The invention relates to an indoor radiation cooling method and a low-temperature radiation plate split air conditioner. The radiation cooling method comprises the following steps: 1) indoor air performs high-volume circulation through an air inlet and an air outlet of a shell with an evaporator, and is dehumidified and cooled; and 2) after the indoor relative humidity reaches a preset value, a radiation plate mounted indoors controls and finely adjusts the indoor air temperature. The high-volume circulation is performed with the indoor air through the air inlet and the air outlet to quickly realize the dehumidification purpose; and after the relative humidity reaches the set value, a small-circulation heat exchange state in a cavity between the radiation plate and the air inlet and the air outlet of the shell is converted to, and the indoor temperature is finely adjusted and controlled through the radiation plate, so that the energy is saved, the human comfort can be improved, and the defect of human feeling uncomfortable caused by high-circulation air flows in a traditional split air conditioner is overcome.

Description

technical field [0001] The invention relates to an indoor radiation cooling method and a low-temperature radiation plate split air conditioner, belonging to the field of air conditioners. Background technique [0002] The indoor unit of the existing split-type air conditioner is equipped with a cross-flow fan and an evaporator. The cross-flow fan runs, and the indoor air passes through the air inlet, air outlet and indoor circulation of the evaporator on the indoor unit shell. This process will not only Noise is generated, and the temperature cannot be fine-tuned. The so-called fine-tuning means that according to the human body in different environments, even if there is a fluctuation of heat transfer within 1%, the air-conditioning heat transfer can be adjusted in a targeted manner. [0003] The air conditioner with the traditional structure also has the following problems. Since the indoor unit dehumidifies and cools the indoor unit through the cold air blown out, the air ...

Problems solved by technology

[0003] The air conditioner with the traditional structure also has the following problems. Since the indoor unit dehumidifies and cools the indoor unit through the cold air blown out, the air flow will also cause extremely uncomfortable feelings to the human body, and when entering the air-conditioned room in summer, it still feels very comfortable. , but after a while there will be a cold feeling; or the temperature has been adjusted to a comfortable temperature before going to bed at night, and it feels too cold in the middle of the night, if you insist on opening it all night, it may even lead to the possibility of cold

[0004] The traditional structural air conditioner still has the defect of wasting a lot of energy. The main reason is that it pays too much attention to the process of cooling, that is, the process of removing sensible heat, and dehumidification is just an accessory of cooling. For example, the indoor humidity is high and the temperature is not very high. In the case of dehumidification, it may cause the temperature to drop too low, which will cause discomfort to the human body
