Modular pressure-bearing heat pump system and control method thereof

Abstract

The invention discloses a modular pressure-bearing heat pump system and a control method thereof, and belongs to the field of heat pump equipment. For solving the problems that in the prior art, the supply pressure of hot water in the existing high-capacity water-consuming system cannot be kept balanced, water for terminals of the water-consuming system suddenly becomes cold and hot, and the capacity tonnage is large, the invention provides the modular pressure-bearing heat pump system and the control method thereof. The modular pressure-bearing heat pump system comprise a main machine, a heating water tank and a plurality of water storage water tanks which are connected in series through circulation pipelines, a water supplementing pipe connected to a tap water municipal pipe network is communicated with the interior of the heating water tank and the first-stage water storage tank, the multiple stages of water storage water tanks are finally communicated with the heating water tank through the circulation pipelines, and the heating water tank is connected with a cold water pipeline and a hot water pipeline of the main machine; and the heating water tank and the last-stage heat storage water tank are communicated with a hot water feeding pipe. According to the modular pressure-bearing heat pump system and the control method thereof, a controller is used for effective setting and controlling, the balance of water pressure of the terminals can be realized, temperature is appropriate, energy consumption is low, and a large amount of power equipment is not needed.

Description

technical field [0001] The invention relates to the field of heat pump systems, and more specifically, to a modular pressure-bearing heat pump system and a control method thereof. Background technique [0002] Traditional water heaters are usually direct heat exchange systems with an integrated structure consisting of vacuum heat collecting tubes directly connected to non-pressurized water tanks. This kind of traditional water heater has high heat exchange efficiency, but its disadvantages are also very obvious: it is large and must be placed outdoors, which is not only inconvenient to install, but also restricts the use of multiple households on the first floor; and the water supply power of the water tank is insufficient because it is in an unpressurized state. [0003] In order to overcome the problem of insufficient power for non-pressurized water supply, a Chinese patent application with the application number 01103950.7 and titled "New Generation Metal Glass Vacuum Tub...
