Embodiment Construction

[0016] The present invention will be further described below, a start-stop control method of a special heat pump water heater coordinated with solar energy, the controller is equipped with an ambient temperature sensor and a hot water temperature sensor, and the controller needs to have a 24-hour clock function. The current season and the temperature of hot water to be prepared are determined by the detected ambient temperature; the equipment adopts different operating modes according to different seasons.

[0017] Real-time detection of ambient temperature T by an ambient temperature sensor 环 , by T 环 Calculate the daily average temperature T 平均 , by T 平均 Determine that the current weather belongs to summer, winter or transitional season and automatically set the temperature T to be reached for hot water production fh . When T 平均 It is summer when ≥25°C, at this time the default T fh =50°C; when 25°C>T 平均 When ≥20℃ is the transitional season, at this time the default T...

Abstract

This invention relates to the field of solar energy heat pump water heater technology, especially a method of starting and stopping the special heat pump water heater cooperated with solar energy. An environmental temperature sensor detects environmental temperature T ring at any time. The T ring calculates the average temperature T average of each day. The T average determines the actual weather belongs to summer, winter or transitional season. A hot water temperature sensor detects the water temperature T hot in the heat preserving water tank at any time. The T hot compares the setting temperature Tfh and determines the starting and stopping of compressor in different seasons and times. This invention can greatly reduce the heating power arrangement of heat pump water heater. It can also reduce the initial cost and resource consumption in the initial cost.

Description

Technical field: [0001] The invention relates to the technical field of solar heat pump water heaters, in particular to a start-stop control method of a special heat pump water heater cooperating with solar energy. Background technique: [0002] Existing solar water heating systems require auxiliary heating to ensure normal use throughout the year. Currently available solar auxiliary heating systems include fuel oil, gas and other boiler auxiliary, electric auxiliary and heat pump water heater auxiliary. [0003] The start-stop control of boiler auxiliary and electric auxiliary is generally to detect whether the hot water temperature reaches the set value at a certain time in the afternoon; if it reaches the set value, the auxiliary heating system will not start, if it does not reach the set value, the auxiliary heating system will start up. Compared with the boiler, the heating power of the heat pump water heater is generally small; if the heating power needs to be increas...
