Air conditioner

Abstract

The invention relates to an air conditioner and belongs to the technical field of air conditioners. The air conditioner comprises a fresh air processor, a cold and hot medium water pipe, a dry coil, a refrigerator, a first three-way valve, a second three-way valve, a temperature detection system and a temperature and humidity adjusting system. The refrigerator is connected with a first cold and hot medium inlet pipe and a first cold and hot medium outlet pipe which are arranged on the fresh air processor through the first three-way valve. The second three-way valve is arranged at the downstream of the joint of the first cold and hot medium outlet pipe. The second three-way valve is connected with a second cold and hot medium inlet pipe and a second cold and hot medium outlet pipe which are arranged on the dry coil, and then the connecting position is connected with the refrigerator. The temperature detection system and the temperature and humidity adjusting system are arranged in the air conditioner. Energy consumption for dehumidification and cooling is treated through the same refrigerator and a cold medium water pipeline system, and gradient temperature difference design is carried out on the cold and hot medium water pipe, so that the manufacturing cost and the occupied space of equipment are reduced, and miniaturization, household use and industrialization of the temperature and humidity independent control air conditioner can be achieved.

Description

technical field [0001] The invention relates to an air conditioner and belongs to the technical field of air conditioners. Background technique [0002] In the prior art, ordinary air conditioners use heat-humidity coupling treatment for the air, and dehumidify the air while cooling down. When the heat-humidity ratio changes, it is easy to cause a certain parameter in the temperature or humidity to lose control, and it is impossible to accurately control the change of temperature and humidity. . Secondly, ordinary air conditioners will produce condensed water when cooling, which is easy to breed bacteria and bring health risks. In addition, due to the heat-humidity coupling treatment of ordinary air conditioners, when fresh air is added, the cooling capacity required for dehumidification is relatively large, and generally does not have a fresh air function. If fresh air is required, an additional fresh air system independent of the air conditioner is usually added, and the ...

Problems solved by technology

[0002] In the prior art, ordinary air conditioners use heat-humidity coupling treatment for the air, and dehumidify the air while cooling down. When the heat-humidity ratio changes, it is easy to cause a certain parameter in its temperature or humidity to lose control, and it is impossible to accurately control the change of temperature and humidity.

Secondly, ordinary air conditioners will produce condensation water during cooling, which is easy to breed bacteria and bring health risks

In addition, due to the heat-humidity coupling treatment of ordinary air conditioners, when fresh air is added, the cooling capacity required for dehumidification is relatively large, and generally does not have a fresh air function. If fresh air is required, an additional fresh air system independent of the air conditioner is usually added, and the price is relatively expensive.

The traditional air conditioner with independent temperature and humidity control adopts separate independent control of temperature and humidity, which can avoid the above problems. Its dehumidification is mainly realized by means of wheel dehumidification and solution dehumidification. The coil is equipped with another set of chillers responsible for preparing high-temperature refrigerant water, and special dehumidification equipment such as rotary dehumidification and solution dehumidification need to heat and regenerate the desiccant, which requires high investment, complicated equipment pipelines, large space in the machine room, and energy consumption for operation. Many, the cooling and dehumidification of the compressor unit increases the number of refrigeration compressors, and also increases the cost, energy consumption and occupied space of the air conditioning system

Therefore, the temperature and humidity independent air conditioning system is usually used in some places with special needs, or public places that need to deal with a large amount of cooling load. Each set of temperature and humidity independent air conditioning system is also specially designed for the place it serves, and ordinary household users usually cannot directly purchase it from the market. to such products
