Problems solved by technology

[0002] At present, domestic hot water devices usually use oil boilers, electric water heaters and solar water heaters. These devices have low thermal efficiency and large primary energy consumption, which is not conducive to environmental protection. Solar water heaters are affected by climate and installation conditions, so it is not very convenient to use.

Abstract

The commercial energy accumulating heat pump water heating system has water pump, solenoid valve and cold water tank connected successively to the inlet pipe of the heat pump water heating machine; the second valve, hot water tank, water pump and energy accumulating hot water tank connected successively to the outlet pipe of the heat pump water heating machine; the third valve connected to the solenoid valve, the fourth valve and energy accumulating hot water tank connected successively to the outlet pipe of the hot water tank; the first valve and energy accumulating hot water tank connected successively to the outlet pipe of the heat pump water heating machine; and the automatic controller for the heat pump water heating system. The present invention is based on the use of heat pump water heating machine and has increased energy accumulating hot water tank for best utilization of the valley electric power.

Description

technical field [0001] The invention relates to an energy storage heat pump hot water system. Background technique [0002] At present, domestic hot water devices usually use oil boilers, electric water heaters and solar water heaters. These devices have low thermal efficiency and large primary energy consumption, which is not conducive to environmental protection. Solar water heaters are affected by climate and installation conditions, so it is not very convenient to use. . Due to the high energy efficiency ratio of the heat pump, the heat pump system has been more and more widely used in the production of hot water devices. [0003] The theoretical basis of the heat pump originated from the papers on the reverse Carnot cycle in the 19th century. It was not until the 1920s and 1930s that the development of heat pump equipment achieved rapid development. At that time, Britain installed the first heat pump that used air as the heat source for hot water supply. In 1937, Jap...
