GLV and fresh air independent temperature-humidity control system and mounting chamber thereof

Abstract

The invention discloses a GLV (Green Landleaf Variable refrigerant flow) and fresh air independent temperature-humidity control system and a mounting chamber thereof. The GLV and fresh air independent temperature-humidity control system comprises a GLV system and a fresh air system, wherein the GLV system comprises a GLV outdoor unit and at least one GLV indoor unit, each of the GLV indoor units is communicated with at least one air supply pipeline and comprises an enclosure, a micro-channel heat exchanger, a sound absorbing baffle and an air feeder, a recirculating air inlet is formed in each enclosure, the micro-channel heat exchangers are connected with the GLV outdoor unit, the air feeders are communicated with air supply pipes, and an air supply outlet is formed in one end part of each air supply pipe; and the fresh air system comprises a dehumidifying fresh air processor and fresh air pipes, one end of each fresh air pipe is communicated with the dehumidifying fresh air processor, a fresh air outlet is formed in the other end of each fresh air pipe, and fresh air sequentially passes through the dehumidifying fresh air processor and the fresh air pipes and finally flows out from the fresh air outlets. The GLV and fresh air independent temperature-humidity control system and the mounting chamber thereof are simple in structure and reasonable in layout, and can effectively reduce system energy consumption and improve the system energy efficiency and the indoor air quality.

Description

technical field [0001] The present invention relates to the technical field of air-conditioning system design, especially a GLV (abbreviation of Green Landleaf Variable Refrigerant Flow, green means green, Landleaf is the name of the applicant Langlv Company, and Variable Refrigerant Flow refers to the variable refrigerant flow system) And fresh air temperature and humidity independent control system and its installation room. Background technique [0002] With the improvement of people's living standards, modern people have higher requirements for the temperature and humidity of living and working environments. The existing air-conditioning fresh air system generally handles temperature and humidity at the same time, that is, the indoor sensible heat load and latent heat load are processed through one system at the same time. There is no phase change, and latent heat refers to the heat absorbed or released by a substance when it changes from one phase to another under isot...

Problems solved by technology

[0003] 1. Energy waste: The existing air-conditioning system uses one system for cooling and dehumidification at the same time. In order to eliminate the residual humidity in the room, the evaporation temperature during cooling often needs to be set to a very low temperature. However, in the air-conditioning system, the sensible heat load accounts for If the total load is more than half, then using a low evaporation temperature to deal with the sensible heat load in the room will cause a waste of energy utilization grade, and although the humidity (moisture content) of the air after cooling and dehumidification meets the requirements, the temperature is too low , sometimes need to reheat, which will cause further waste and loss of energy;

[0004] 2. It is difficult to adapt to the change of heat-humidity ratio: The heat-humidity ratio actually required by the building has a wide range of changes. Generally, the control of humidity is sacrificed, and the indoor relative humidity is too high or too low to compromise by only meeting the requirements of indoor temperature. If the relative humidity is too high, it will lead to discomfort, but by lowering the room temperature to improve thermal comfort, it will cause unnecessary increase in energy consumption. Increase;

[0005] 3. Deterioration of indoor air quality: most air conditioners cool and dehumidify the air through the surface cooler, which causes the surface of the surface cooler to become wet and even accumulate water. After the air conditioner is shut down, the wet surface of the surface cooler becomes a breeding ground for mold ideal place, which may affect the health problems of users;

[0006] 4. The traditional indoor terminal device has limitations: the traditional indoor terminal device is set on the top of the room, and adopts the air outlet form of top return and top air supply. The top air supply will make the human body have a strong sense of blowing, and the comfort is low
