Capillary network radiation refrigeration air conditioning system and anti-dewing method

Abstract

The invention discloses a capillary network radiation refrigeration air conditioning system and an anti-dewing method. The capillary network radiation refrigeration air conditioning system is characterized in that a spraying device (2), an absorption tower (3) and less auxiliary devices are only additionally arranged; an absorption / analysis water steam principle of absorption type working pairs isfully utilized, operation pressure, temperature and flow conditions of the absorption type working pairs are controlled, the cooling capacity is provided for capillary network radiation refrigerationcirculation distributed in a room (5) through an evaporator (7), and simultaneously, the natural air with higher outdoor temperature and humidity can be firstly dehumidified by utilizing the absorption type working pairs, and then the dehumidified natural air (21) can be pre-cooled by utilizing frozen water (23) formed in an outlet of the evaporator (7), is then fed into the room and is used as fresh air. Compared with relatively-conventional air conditioning adopting an independent capillary network radiation refrigeration and independent fresh air system, the method disclosed by the invention is simple to operate, and can avoid the dewing problem of conventional capillary radiation refrigeration tube network, and therefore, the method is particularly suitable for energy-saving reconstruction of the area radiation refrigeration air conditioning with higher humidity and temperature, and is also suitable for being used in occasions on which the temperature and the humidity need to be accurately controlled.

Description

technical field [0001] The invention provides a capillary network radiation refrigeration air-conditioning system and an anti-condensation method, belonging to the field of energy systems. Background technique [0002] Conventionally, the wall-mounted or cabinet-type air conditioners that arrange the evaporator indoors mainly use the steam refrigeration cycle to continuously cool the indoor circulating air, thereby realizing the regulation of the room temperature and humidity. In order to ensure the cooling effect of the room, the temperature of the refrigerant in the evaporator is generally much lower than the set temperature of the room, there is a temperature difference of 10-15°C, and the heat transfer temperature difference of the outdoor condenser is also 10-15°C, so this type of air conditioner COP is lower. [0003] A capillary network radiation refrigeration air-conditioning system developed in recent years is an air-conditioning method with independent control of ...

Problems solved by technology

[0004] However, for high-temperature and high-humidity areas, since the dew point temperature of the outdoor air is higher than the cooling temperature in the room, capillary network radiation air conditioning is used for it, and there is a hidden danger of condensation on the pipe network layout surface, which is easy to breed bacteria, corrode and pollute the wall surface , thus limiting the vigorous promotion of capillary network radiative refrigeration and air conditioning in these areas
