Multi-mode operation control method and control device for restaurant kitchen heat pump system

Abstract

The invention discloses a multi-mode running control method and device for a restaurant kitchen heat pump system and relates to control of a heating and cooling combined system, in particular to a control method and equipment of a heat pump integrated system applicable to hot water supply, cooling, dehumidifying, refrigeration and preservation of restaurant kitchens. The control device controls a multi-mode refrigerant circulating loop switching mechanism to change circulating path of refrigerant by detecting and comparing measured value and set value of running mode parameters, and controls the heat pump system of the restaurant kitchens to run according to the preset running modes; by the multi-mode running control method and device, automatic running of seven running modes including an in-situ water heating and refrigeration mode, a water heating mode, a refrigeration mode, an oil removal mode, a water heating, refrigeration and cooling mode, a hot air heating, refrigeration and cooling mode and a hot-water heat preservation, refrigeration and cooling mode are realized, control is flexible and convenient, environment friendly and energy saving, and running efficiency is high; the control device is a built-in microcontroller and installed with software function modules to realize multi-mode running control and has the advantages of compact structure, flexibility and reliability in functions and low manufacturing cost.

Description

technical field [0001] The invention relates to the control of a combined heating and cooling system, in particular to a control method and equipment for a heat pump integrated system suitable for hot water supply, cooling and dehumidification, and refrigeration and preservation in the back kitchen of a restaurant. Background technique [0002] The kitchen is the place to cook delicious food, and it is an important part of quality life enjoyment. The catering industry is also developing at a relatively fast speed in China. Whether the restaurant food is healthy and delicious is the foundation of the restaurant's survival. As the temperature rises gradually, all kinds of bacteria in the kitchen are more likely to breed in high-temperature and high-humidity environments. They will hide in every subtlety that we are not easy to detect, endangering our health. The chef plays a vital role here. However, the environment of the restaurant kitchen has always troubled them.
