Multiple variable-flow household water system central air condition

Abstract

The invention relates to a multiple variable-flow household water system central air condition. An energy storing water tank forms a closed water system together with the pipelines of the tail end in each chamber and pipelines among the chambers. The water outlet of the energy storing water tank is firstly connected with a constant-voltage frequency converting device and then is respectively connected to the water inlet of the tail end in each chamber through the pipelines; the water outlet pipeline of the water outlet of the tail end in each chamber is provided with an electric valve; the pipelines between the water outlet of the energy storing water tank and the constant-voltage frequency converting device are also connected to a constant-pressure expansion water tank through branch pipelines; the liquid level of the constant-pressure expansion water tank is higher than the highest point of the liquid level in the closed water system; the constant-pressure expansion water tank also takes the effect of making the pressure of the water inlet of the constant-voltage frequency converting device constant while automatically supplementing water for the system; the constant-voltage frequency converting device can be automatically started or stopped according to the working state of an indoor machine unit to achieve the goal of energy saving and consumption reduction, and the frequent starting and stopping phenomena of a heat pump machine unit under the low load condition of the indoor machine unit are also effectively reduced, thereby reducing the operating energy consumption of the heat pump machine unit and prolonging the service life of the machine unit.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a multi-connected variable flow household water system central air conditioner suitable for independent families or other small places. Background technique [0002] With the rapid development of economy and technology, the application of central air-conditioning has broken through the traditional application places, such as large-scale public, productive and commercial buildings, and quickly entered high-end residences and other places with high requirements for space environment. . Central air-conditioning is accepted by more and more people for its unique comfort and coordination with indoor and outdoor space environment. [0003] Household central air conditioners are small central air conditioners, which inherit the comfort and aesthetics of central air conditioners, as well as the convenient control and flexibility of household air conditioners; at the...

Problems solved by technology

[0009] c. Under the condition of "big horse-drawn carts", due to the small capacity of the household air-conditioning water system, the main engine frequently starts and stops, resulting in: I The comfort of the air conditioner is reduced due to the large fluctuation of the medium water temperature; II The frequent start and stop of the high-power main engine Stopping increases the operating power consumption and affects the stability and service life of the host

[0010] d. The overflow of refrigerant water in the non-working terminal equipment has a great hidden danger of condensation water in summer high temperature and high humidity environment

[0011] e. Due to the small size of the household air-conditioning system (small change in pressure difference), the large change in indoor use load, and the special configuration relationship between the air-conditioning host and the indoor load, variable flow technologies such as differential pressure bypass used in conventional air-conditioning projects are not suitable for this type of project. cannot be used in the system
