Novel header type heat storage radiant plate type indoor heat exchanger for winter and summer

Abstract

The invention discloses a novel header type heat storage radiant plate type indoor heat exchanger for winter and summer. The exchanger comprises a plurality of radiant plate type heat exchange sheets,the radiant plate type heat exchange sheets comprise radiation plate interlayers, N rows of heat exchange pipe bundles are arranged in the radiation plate interlayers from top to bottom, wherein n equals 3-20; in the heat exchange pipe bundles, an included angle between the heat exchange pipe bundles of odd-numbered lines and the horizontal direction is alpha, and an included angle between the heat exchange pipe bundles of even-numbered lines and the horizontal direction is minus alpha, and heat exchange pipe bundles are composed of 2-4 parallel copper pipes; the left and right ends of the heat exchange sheet interlayers are correspondingly provided with refrigerant collecting and distributing devices communicating with the heat exchange pipe bundles, the refrigerant collecting and distributing devices are internally divided into a plurality of refrigerant channels from top to bottom through baffle plates, the refrigerant channels communicate with two-adjacent-row heat exchange pipe bundles, so that the n rows of heat exchange pipe bundles communicate to form an entire channel; and a heat storage medium fills space between the radiation plate interlayers and the heat exchange pipebundles. According to the exchanger, the manufacturing process is simple, the system energy efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to an air source heat pump refrigeration and heating system, in particular to a header-type thermal storage radiation plate indoor heat exchanger for both winter and summer that can be matched with an air source heat pump unit. Background technique [0002] In today's world, with the rapid development of economy, problems such as energy shortage, increasingly serious environmental pollution and sustainable economic development have gradually entered people's field of vision. In my country, the traditional heating energy in the northern region is dominated by coal, and the huge pollution caused by coal combustion has attracted great attention from the country. Since 2016, the state has successively implemented clean heating "coal-to-electricity" projects in Beijing, Tianjin, Hebei and surrounding areas, striving to promote clean heating in winter in northern regions. Among the many technologies of clean heating, air source heat pu...

AI Technical Summary

Problems solved by technology

In winter, hot air indoor units are used for heating, which is prone to produce a feeling of blowing and affect thermal comfort

Another form of heating is to use hot water terminal, but the secondary heat exchange between the system and water will cause a certain amount of heat loss, and it is only suitable for heating in winter, and a traditional blower air conditioner is required for cooling in summer

In addition, frosting on the surface of the outdoor evaporator in winter is an unavoidable problem during the operation of the air source heat pump. Intermittent shutdown and defrosting will easily affect the stability of the indoor temperature and reduce thermal comfort.
