Single-pipe efficient refrigeration, dehumidification and heating air conditioning conversion system

Abstract

A single-pipe efficient refrigeration, dehumidification and heating air conditioning conversion system comprises an outdoor unit exchange system and an indoor exchange system. The outdoor unit exchange system is composed of a compressor, a four-way reversing valve, an outdoor fan, an outdoor surface air cooler, a gas phase stop valve, a liquid phase stop valve, an electronic expansion valve, an outdoor one-way valve and an outdoor electromagnetic valve. The indoor unit exchange system comprises an indoor surface air cooler, an evaporator, an indoor fan, a throttling capillary tube, an indoor one-way valve, a first indoor electromagnetic valve, a throttling valve and a second indoor electromagnetic valve, the gas phase stop valve is connected with a gas valve connector of the indoor unit exchange system through a gas pipe, and the liquid phase stop valve is connected with a liquid valve connector of the indoor unit exchange system through a liquid pipe. According to the scheme, a single pipe is adopted, the cost is reduced, the complexity of the installation process is simplified, and the reliability is improved. Meanwhile, evaporation area of the indoor surface air cooler is enlarged in the refrigeration process, so that the energy efficiency ratio is increased, a certain liquid storage effect is achieved, and the dehumidification mode can be decided to be adopted according to actual requirements.

Description

technical field [0001] The invention relates to a single-pipe fresh air conversion system for high-efficiency refrigeration, dehumidification and heating, which belongs to the field of air conditioning equipment. Background technique [0002] At present, air-conditioning equipment (including air conditioners and fresh air switches, etc.) uses cooling and heating systems. Dehumidification is also realized by cooling functions. It belongs to cooling and dehumidification, and a small part has added heating and dehumidification functions. At least 3 pipes are connected, and the dehumidification is in the form of heating and dehumidification. On the one hand, the connection of multiple pipes is complicated, the installation is troublesome, and the reliability is poor; Not high either. Generally speaking, this form fails to choose to achieve heating, isothermal or cooling and dehumidification according to actual requirements, and the energy consumption is high. Contents of the ...

Problems solved by technology

[0002] At present, air-conditioning equipment (including air conditioners and fresh air switches, etc.) uses cooling and heating systems. Dehumidification is also realized by cooling functions. It belongs to cooling and dehumidification, and a small part has added heating and dehumidification functions. At least 3 pipes are connected, and the dehumidification is in the form of heating and dehumidification. On the one hand, the connection of multiple pipes is complicated, the installation is troublesome, and the reliability is poor; not high

Generally speaking, this form does not achieve the choice of heating, isothermal or cooling dehumidification according to actual requirements, and the energy consumption is high.
