Description
技术领域technical field
本实用新型属于热泵制热设备技术领域，具体涉及一种基于餐饮余热的热泵热水器。The utility model belongs to the technical field of heat pump heating equipment, in particular to a heat pump water heater based on waste heat from catering.
背景技术Background technique
热水供水系统是大型餐饮中心基础设施的重要组成部分，其热水耗费能源约占整个饭店总能源的20％至40％，因此热水供应系统的稳定性和节能性，直接影响到大型餐饮中心热水供水系统的经济性、能源消耗和安全性。The hot water supply system is an important part of the infrastructure of large-scale catering centers. The energy consumed by hot water accounts for about 20% to 40% of the total energy of the entire hotel. Therefore, the stability and energy saving of the hot water supply system directly affect the Economics, energy consumption and safety of central hot water systems.
热泵热水器应用热泵技术，通过热力循环，在消耗部分电能的基础上，从周围环境中吸收热量将水进行加热。但是如果环境温度较低(冬天或者严寒地区)，热泵的制热效率降低，将无法满足热水供应量的需求，此时需要开启辅助加热器加热热水，电耗量大，加热成本高。Heat pump water heaters use heat pump technology to heat water by absorbing heat from the surrounding environment on the basis of consuming part of the electric energy through a thermodynamic cycle. However, if the ambient temperature is low (in winter or in severe cold regions), the heating efficiency of the heat pump will decrease, which will not be able to meet the demand for hot water supply. At this time, it is necessary to turn on the auxiliary heater to heat the hot water, which will consume a lot of electricity and cause high heating costs.
大型餐饮中心含有丰富的余热资源，其余热资源可分为两个部分，一部分为蒸汽余热资源，另一部分为污水余热资源。现实生活中，人们大多忽略了余热资源，造成能源的浪费。Large-scale catering centers contain abundant waste heat resources, which can be divided into two parts, one part is steam waste heat resources, and the other is sewage waste heat resources. In real life, people mostly ignore waste heat resources, resulting in a waste of energy.
