New air dehumidification system with double heat exchange cores

Abstract

The invention discloses a new air dehumidification system with double heat exchange cores. The system comprises a sensitive heat exchange core, a total heat exchange core, an evaporator, a first condenser, a second condenser, a compressor, a four-way reversing valve, a bidirectional expansion valve, an air exhaustion blower and an air feeding blower, wherein the compressor is sequentially connected with the second condenser, the four-way reversing valve, the first condenser, the bidirectional expansion valve and the evaporator by a refrigerant conveying pipeline; the air feeding blower is arranged on one side of the first condenser; the air exhaustion blower is arranged on one side of the second condenser; the sensitive heat exchange core is arranged at an indoor air return inlet; and the total heat exchange core is arranged at an indoor new air inlet. The new air dehumidification system disclosed by the invention has a simple structure and a good energy-saving effect and is convenient to use; the pre-cooling of the new air can be realized without external energy sources, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning and air treatment, in particular to a fresh air dehumidification system provided with double heat exchange cores. Background technique [0002] The air conditioning system aims to provide a controllable, comfortable and healthy air environment for people's indoor activity space or provide specific air environment conditions for storage, processing, equipment operation and other activity spaces. The main controls of air conditioning include air quality, air temperature, air humidity, and wind speed. [0003] The natural and effective way to control air quality is to use outdoor fresh air to replace or dilute indoor air, that is, to inhale outdoor fresh air and discharge indoor exhaust air. For existing fresh air devices, fresh air in high-humidity environments generally The moisture in the fresh air is condensed through the condensation pipe to achieve the purpose of dehumidification of t...

AI Technical Summary

Problems solved by technology

[0005] 1. No pre-cooling section is installed, resulting in excessive compressor configuration, increased energy consumption, increased equipment volume, and increased noise interference

[0006] 2. The use of external cold water cooling source for pre-cooling treatment increases the complexity of the system and requires additional external pipes and components, resulting in large energy loss and low energy efficiency
