Combined air conditioning unit system

Abstract

The invention discloses a combined air conditioning unit system which comprises an air processing function section assembly and an air circulation heat pump. The air processing function section assembly comprises a fresh air section, an air return section, a mixing section, a coarse filtering section, a surface cooling section, a reheating section, a fan section, an efficient filtering section andan air outlet section. The air circulation heat pump comprises an air compressor, a turbine air compression component and an air / water heat exchanger, wherein the air inlet end of the air compressorcommunicates with the fresh air section, the air exhaust end of the air compressor is connected with the air inlet end of an air compression component, the air exhaust end of the air compression component is connected to the air inlet end of a turbine component through the air / water heat exchanger, the air exhaust end of the turbine component communicates to the mixing section, a water path inletof the air / water heat exchanger is connected with a reheating coil pipe water outlet of the reheating section, and a water path outlet of the air / water heat exchanger is connected to a water inlet ofa reheating coil pipe through a circulation water pump. According to the unit system, heat is provided for the reheating section while part of fresh air is precooled, energy consumption in the air processing process can be reduced, and thus the purpose of energy saving is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a combined air conditioning unit system. Background technique [0002] The combined air conditioning unit is a kind of air handling equipment assembled from various air handling functional sections. It is an important equipment at the end of the central air conditioning and undertakes the task of heat and humidity treatment of the air. Widely used in air conditioning systems. [0003] For combined air conditioning units, the same cold water coil is usually used in summer to treat the air to the dew point temperature for cooling and dehumidification. However, for comfort air conditioners, the temperature difference of the supply air should not be greater than 10°C, so it is often necessary to further increase the temperature of the air at the dew point temperature to meet the requirements of the temperature difference of the supply air. In addition, for technological ai...
