Fresh air and cold and hot air conditioner distributed integrated equipment for residences and control system

Abstract

The invention discloses fresh air and cold and hot air conditioner distributed integrated equipment for residences and a control system. The fresh air and cold and hot air conditioner distributed integrated equipment comprises a fresh air system module and one or more mixed air cold and hot source system modules, the fresh air system module comprises a fresh air control system and a fresh air outlet, and the mixed air cold and hot source system module comprises a fresh air inlet, a mixed air control system, a circulating air inlet, a refrigerant or cold and hot water coil pipe and a third fan;and the fresh air outlet communicates with the fresh air inlet through an air pipeline. The fresh air and cold and hot air conditioner distributed integrated equipment is characterized in that freshair at the fresh air inlet and circulating air at the circulating air inlet are mixed through then third fan and then introduced into the coil pipe, and the center line of the third fan and the centerline of the coil pipe are located on the same plane. The fresh air and the circulating air are mixed in the third fan firstly and then introduced into the refrigerant or cold and hot water coil pipe,the fresh air and the circulating air pass through the refrigerant or cold and hot water coil pipe after the temperature of the fresh air and the temperature of the circulating air are unified, and the effect of precisely adjusting the temperature is achieved.

Description

technical field [0001] The invention relates to technical fields such as fresh air, air conditioning, and dehumidification, in particular to a split-type fresh air and air conditioner integrated machine with low noise and high refrigeration efficiency, and in particular to a distributed integrated equipment and control system for residential fresh air and cold and hot air conditioners. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's quality of life. People have gradually shifted their goal from the basic needs of having a house to live and food to a high-quality life. More and more attention is paid to indoor air quality. At present, most households have only air conditioners but no fresh air, or have fresh air fans but there is a lot of noise. Existing equipment cannot meet people's high requirements for indoor comfort. In response to the above problems, a household fresh air and air conditioner integrate...

AI Technical Summary

Problems solved by technology

However, the structure of the above-mentioned fresh air air conditioning system patent application mainly has the following disadvantages: (1) After the integration, there are generally three fans in one chassis, and the fresh air blower and the circulating air blower are connected in parallel, but the air volume and wind pressure of the fans are different. , the air volume and pressure of the circulating air supply fan are much greater than that of the fresh air supply fan, resulting in uneven mixing of fresh air and circulating air. It is difficult to achieve the required fresh air volume when the fresh air volume needs to be adjusted

In addition, when the fresh air and return air pass through the refrigerant coil, the temperature is inconsistent, which will cause the cooling efficiency and heating efficiency to drop, which is not conducive to energy saving, and the air pipe size cannot be installed reasonably due to the large size of the air duct.
