Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following descriptions of the specific implementations are only exemplary, and it should be understood that the specific implementations described here are only used to explain the present invention, but not to limit the present invention and its application or usage.

[0051] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. In con...

Abstract

The invention relates to a method for controlling the on-off quantity of a heat pump unit, wherein the total number of modular heat pump units is detected as N1, and all N1 modular heat pump units arestarted to complete a first heating cycle; the modular heat pump unit running time is recorded as T1, and the T1 and the range of the set modular heat pump unit running time t is compared to judge that the number of the modular heat pump units started in the second heating cycle is N2. The operation time of the modular heat pump unit in the second heating cycle is consistent with the setting to complete a heating cycle for the water tank and the range requirement of the modular heat pump unit running time, thus effectively avoiding the problem of frequent start and stop of the unit caused byan improper selection of the unit or the water tank, prolonging the service life of the unit and reducing the operation cost of the unit. Meanwhile,a heat pump unit system is provided.

Description

technical field [0001] The invention relates to the technical field of heat pump systems, in particular to a method for controlling the number of on-off heat pump units and a heat pump unit system. Background technique [0002] Generally, hot water consumption is large in commercial places, such as baths, hotels, schools and dormitories. The hot water heating capacity of a single heat pump unit is limited, so the project generally adopts the joint operation of multiple modules for hot water supply. However, when the unit is operated in a modular manner, if the water tank is not properly selected, it is easy to cause the unit to start and stop frequently. The frequent start and stop of the unit will cause great damage to the heat pump unit, which will greatly shorten the service life of the heat pump unit. Contents of the invention [0003] The purpose of the present invention is to solve the problem of frequent start and stop of heat pump units by providing a method for ...
