Embodiment Construction

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] see figure 1 Constant humidity refrigeration method in preferred embodiment of the present invention, comprises the following steps:

[0020] In step S110, the set target ambient temperature T is obtained, and the indoor ambient temperature T1 and the preset target humidity (same as relative humidity) range RH, ie range, are obtained at preset time intervals.

[0021] Specifically, the target ambient temperature T set by the user is acquired through a sensor. In addition, it is also necessary to obtain the indoor ambient temperature T1 at preset intervals....

Abstract

The invention provides a constant-humidity refrigeration method and a system. The method comprises the following steps: a set target environment temperature is obtained, and an indoor environment temperature and a preset target humidity range are obtained every preset time; a dew point temperature is looked up from a table according to the obtained indoor environment temperature and preset target humidity range; the found dew point temperature is set as a target evaporation temperature of the operation of an air conditioning evaporator; and an operation frequency of a compressor is adjusted according to a difference value between a present evaporation temperature and the target evaporation temperature of the air conditioning evaporator until the indoor environment temperature reaches the target environment temperature. When the indoor target environment temperature is precisely controlled, the indoor humidity is guaranteed without causing excessive indoor dryness, so that the uncomfortable body condition of users is prevented, and the user experience of air conditioners is enhanced.

Description

technical field [0001] The invention relates to air conditioning technology, in particular to a constant humidity refrigeration method and system. Background technique [0002] In today's life, people not only have requirements for changes in the appearance and performance of air conditioners, but also pay more and more attention to comfort. Cooling in summer, the room temperature drops too fast when the air conditioner is cooling, it is easy to cause the room to be dry and cause physical discomfort; if the temperature drops too slowly, the effect will deteriorate. How to find a suitable temperature drop / temperature rise rate is the key to improving the comfort of air conditioners. Contents of the invention [0003] The purpose of the present invention is to provide a constant-humidity refrigeration method and system, aiming at solving the problem that the room temperature drops too fast when the air conditioner is cooling, which easily causes the room to be dry and cause...
