Regional system with cooling, heating and hot-water supplying functions and control method thereof

Abstract

The invention discloses a regional system with cooling, heating and hot-water supplying functions and a control method thereof. The regional system with cooling, heating and hot-water supplying functions is composed of a domestic hot water storage tank, an air conditioner end system, a ground source heat exchange system and a water source heat pump unit. The regional system with cooling, heating and hot-water supplying functions is capable of solving the requirements of buildings in cooling, heating and hot-water supplying. The regional system with cooling, heating and hot-water supplying functions can be used for refrigerating in summer, and the water source heat pump unit can be used for heating in winter, so that the domestic hot water can be prepared in spring, autumn and winter; in combination with an advanced machine room control method, a set of complete warm-cold hot water requirements are provided for buildings; and the regional system with cooling, heating and hot-water supplying functions is energy-saving and environment-friendly and is widely applied to places such as a restaurant, a hotel, a hospital, a house and the like.

Description

[0001] technical field [0002] The invention relates to the field of ground source heat pump systems, in particular to a regional triple power supply system and a control method thereof. Background technique [0003] In order to meet the needs of cooling, heating and hot water supply in the existing ground source heat pump system, when the project is large, it is generally equipped with multiple water source heat pump units. The control brings great challenges: First, multiple units generally adopt the problem of waterway summarization. When the load is low, the number of units turned on is small, and the working conditions of each unit cannot communicate and feedback each other. If the total water flow is reduced due to the load , the water flow of each unit is reduced, the air-conditioning effect and the safety of the unit are poor; secondly, when the demand for cooling, heating and hot water is mixed, the number of operating units and accessory equipment are large, and t...

[0003] In order to meet the needs of cooling, heating and hot water supply in the existing ground source heat pump system, when the project is large, it is generally equipped with multiple water source heat pump units. The control brings great challenges: First, multiple units generally adopt the problem of waterway summarization. When the load is low, the number of units turned on is small, and the working conditions of each unit cannot communicate and feedback each other. If the total water flow is reduced due to the load , the water flow of each unit is reduced, the air-conditioning effect and the safety of the unit are poor; secondly, when the demand for cooling, heating and hot water is mixed, the number of operating units and accessory equipment are large, and the workload and workload of the staff in the computer room The difficulty increases, which is not conducive to the normal and fast work of the system. Third, in the case of separate management, the cumulative running time of each equipment cannot be balanced, resulting in uneven equipment wear
