Series single cold and heat source ventilation humidity regulating unit

Abstract

The invention belongs to a ventilation humidity regulating unit, and particularly relates to a series single cold and heat source ventilation humidity regulating unit. The ventilation humidity regulating unit comprises an indoor unit and an outdoor unit, wherein the indoor unit comprises an air inlet, a filter screen assembly, an evaporator, a reheat condenser, a humidifier, a fan and an air outlet which are arranged in sequence; and the outdoor unit comprises a four-way valve, a compressor, a condenser and an outdoor expansion valve, wherein the compressor, the condenser and the outdoor expansion valve form a loop with the evaporator, the evaporator, the compressor and the condenser are connected with the four-way valve, a radiator is arranged on the condenser, the reheat condenser is arranged between the condenser and the evaporator in series through a pipeline, and a reheat expansion valve is arranged on the pipeline where the reheat condenser is located in parallel. According to the series single cold and heat source ventilation humidity regulating unit, a single cold and heat source is adopted to process air, the heating temperature of the reheat condenser is controlled by regulating the flow of the reheat expansion valve, stepless regulation can be realized, the regulation process is simple and flexible, and the indoor unit and the outdoor unit are connected through two pipelines, so that the installation and connection difficulty is reduced.

Description

technical field [0001] The invention belongs to a fresh air humidity control unit, in particular to a series-type single cold and heat source fresh air humidity control unit. Background technique [0002] With the improvement of the quality of life, people's requirements for the living environment continue to increase. In the home and work environment, there are not only fresh air systems for indoor and outdoor ventilation, but also corresponding air treatment equipment for air temperature, humidity, and PM2.5 content in the air. For a new house, the air-conditioning equipment that can be selected includes fresh air purification system for indoor and outdoor ventilation, air-conditioning system for adjusting indoor temperature, dehumidification system for adjusting indoor humidity, winter humidification system, etc. Too many pipeline designs Not only is the installation difficult, but it also increases the design and construction costs, and also brings troubles to subsequen...
