Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, and in particular to a double-return air channel cloud intelligent energy-saving constant temperature and humidity combined air conditioning unit. Background Art

[0002] With the rapid development of biomedicine and high-end manufacturing industries, the market has greater and higher requirements for controlled environments with constant temperature and humidity and cleanliness. At the same time, the energy consumption brought about by constant temperature and humidity and clean environment control is very large. How to reduce one-time investment, reduce maintenance costs, and achieve optimal energy saving is the huge market demand for the unlimited pursuit and development of constant temperature and humidity clean air conditioning in the biomedicine and industrial fields.

[0003] The existing dual-channel technology or dual-meter independent control technology of temperature and humidity has the disadvantages of too large a one-time investment or the inability to self-regulate and control in different seasons, and each debugging and adjustment causes changes in indoor pressure, resulting in extremely high maintenance costs. Therefore, a dual-return air channel cloud smart energy-saving constant temperature and humidity combined air conditioning unit is proposed. Utility Model Content

The application of this technology solves the fatal point that the humidity cannot reach the control requirements due to the excessive air volume processed by the refrigerated water meter cooler during the dehumidification process in summer. At the same time, in order to achieve the humidity standard, the supply air temperature may be too low, and the controlled environment temperature may be too low, and thermal compensation heating is required, resulting in serious double energy consumption in which the energy consumption of thermal compensation heating is increased and the energy consumption of cooling is also increased.

By setting a double return air valve, the air volume of the dual channels can be adjusted under the condition of a constant pressure difference in a controlled environment, and the constant total air volume, constant pressure, constant temperature and constant humidity in the controlled environment can be achieved without heat compensation, thereby achieving the minimum cooling and energy consumption of the combined air cabinet and achieving the maximum energy-saving method of keeping the above four major indicators of air volume, pressure difference, temperature and humidity constant, and the one-time investment is relatively small, and the market applicability and energy saving are excellent.
