Novel cold and heat exchange system of heating ventilation air conditioner

Abstract

The invention provides a novel cold and heat exchange system of a heating ventilation air conditioner. The novel cold and heat exchange system comprises a heat exchange box, lighting heating equipment connected with the heat exchange box and a heating box. A heat absorption partition plate is arranged in the heat exchange box and divides the heat exchange box into an upper hot air box communicating with the lighting heating equipment and a lower hot water box communicating with the heating box. A water medium of the heating tank flows through the heat exchange tank, and hot gas of the upper hot gas tank reheats the water medium flowing through the heat exchange tank and then enters the lower hot water tank; the device further comprises water curtain equipment, the lower hot water tank is connected with the water curtain equipment through a first pipeline, and the water curtain equipment conveys the heat dissipation water medium back to the heating tank through a second pipeline. According to the description, the lighting heating equipment is matched with the heating box for auxiliary heating, the temperature of a medium flowing through the interior of the heat exchange tank is stable, the water curtain equipment is adopted for efficient heat exchange, the working condition workshop temperature is stable, and the characteristics of low cost and high efficiency are achieved.

Description

technical field [0001] The present application relates to the field of cold and heat exchange, and in particular, to a new type of cold and heat exchange system for HVAC. Background technique [0002] With the rapid development of social economy, HVAC is an air conditioner with functions of heating, ventilation and air conditioning. Since the main functions of HVAC include: heating, ventilation and air conditioning, the abbreviation takes the comprehensive abbreviation of these three functions, that is, HVAC. HVAC needs to use heat exchangers for operation. It is a device used to transfer heat from a hot fluid to a cold fluid to meet the specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways and can be divided according to their operation process. It is divided into three categories: partition type, hybrid type and regenerative type; according to the compactness of ...

Problems solved by technology

[0003] However, HVAC has not shown outstanding effects in fields such as working workshops or large-scale event spaces. Due to the large area inside the working workshop, the temperature of the working workshop in a series of processing enterprises in winter is always kept low, and workers need to Wear heavy and warm clothes to keep out the cold and carry out process operations at the same time; the temperature of the workshop under working conditions remains high and cannot be completed

The main reason is that the power consumption required for heating is relatively large, coal-fired heating does not meet national standards and causes waste of non-renewable resources, and the use of geothermal wells is expensive and causes a lack of groundwater, resulting in the inability to improve the working environment
