Description
Technical Field
The utility model belongs to the technical field of temperature and humidity control, it relates to a change amount of wind and refrigerant flow dehumidification device that adjusts the temperature specifically to say so.
Background
The working principle of the common freezing type dehumidifier is as follows: the refrigeration compressor compresses low-temperature low-pressure refrigerant gas into high-temperature high-pressure refrigerant gas, heat is conducted to air pushed by a fan and flowing through fins at a condenser (fin type heat exchanger) part to be changed into high-temperature high-pressure liquid, then the liquid is changed into low-temperature low-pressure liquid after flowing through a capillary tube in a throttling expansion mode, the liquid is evaporated into low-temperature low-pressure gas after the evaporator (fin type heat exchanger) absorbs the heat in the air flowing through the fins, meanwhile, the surface of the evaporator is rapidly cooled to be in an ice-cold state, and the low-temperature low-pressure refrigerant gas is sucked by the compressor and compressed to enter the next circulation process. When the temperature of the humid air is reduced to be below the dew point when the humid air flows through the surface of the ice-cold evaporator, the moisture in the air is condensed out and collected and then discharged, and the moisture content of the humid air is reduced, namely the dehumidification process.
According to the law of conservation of energy, energy cannot be spontaneously extinguished, and only can be converted and transferred. In the working process of the dehumidifier, the compressor continuously inputs electric energy and outputs mechanical energy to do work on the refrigerant gas, then the mechanical energy is converted into heat energy to be transmitted to the refrigerant and the dehumidifier body (including the compressor), and the heat energy is transmitted to air in a condensation link and is brought into an indoor space along with air supply. Therefore, the temperature of the outlet air (also called supply air) is higher than that of the inlet air (also called return air) by about 3-8 ℃ in the dehumidification process (the value is different according to different heat dissipation conditions of the installation position of the dehumidifier), the indoor air continuously accumulates heat generated by the work of the compressor, and the indoor temperature is gradually increased.
Obviously, the dehumidifier achieves the dehumidification purpose and simultaneously increases the air supply temperature and the space temperature, when the indoor environment needs to be cooled and dehumidified in a high-temperature and high-humidity area in summer, the accompanying environment temperature rise needs to increase the refrigeration load of an air conditioner indoor unit (or a fan coil) or a radiation ceiling (or a wall surface or a ground surface) which plays a role in cooling so as to achieve the cooling purpose, and thus secondary side effects of enhancing the blowing feeling of the indoor unit, increasing the noise, weakening the indoor cooling effect of the radiation surface and the like, which reduce the comfort of a human body, are brought.
At present, some dehumidifier manufacturers add a cooling heat exchanger connected to an external low-temperature cold water source for heat exchange at the tail of the dehumidifier, so that the air supply temperature can be reduced according to requirements.
However, the solution of adding a cooling heat exchanger of an external cold water source at the end of the dehumidifier has the following disadvantages: when the dehumidifier works, the dehumidifier is required to rely on an external cold water preparation system, a cold water device or system with a complex structure and high power (most of the prior air-conditioning cold and hot water units with more than 3) is arranged to provide a cold water source, and a cold water circulating pipeline with a considerable length is also arranged. For example, in the time period (transition season) that the temperature is not high in the end of summer, when a local small space (such as only one small room) needs to maintain comfortable constant temperature and humidity, the dehumidifier still needs the cooperative work of a cold water system, and the simple requirement is realized by using a complex and high-energy-consumption equipment system. Meanwhile, in the process of transferring the heat energy (converted by electric energy) generated by the dehumidifier to the outdoor, the solution comprises the following steps: 3 heat transfer steps from air to cold water, from cold water to refrigerant and from refrigerant to outdoor atmosphere, wherein each step has heat exchange efficiency loss, so that the more steps, the lower the efficiency, and the higher the energy consumption.

Meanwhile, the process of transferring the heat energy (converted by electric energy) generated by the dehumidifier to the outside is completed by only transferring the refrigerant to the air in one step, so that the efficiency is improved, and the energy consumption is reduced.
