Air-source modular three-in-one air-conditioning hot water system

Abstract

The present invention discloses an air-source modular three-in-one air-conditioning hot water system, comprising a host and other components. An air-conditioning controller is connected with the host via a control line. A domestic hot water controller is connected with the host through a control line. An inlet for a refrigerant of a domestic hot water tank is connected with a first heat recovery stop valve, and an outlet for the refrigerant of the domestic hot water tank is connected with a second heat recovery stop valve. A built-in plate-type heat exchanger is connected with a floor-heating manifold through a water pipeline, is connected with a first indoor unit through an electric two-way valve of the first indoor unit, and is connected with a second indoor unit through an electric two-way valve of the second indoor unit. An air-conditioning pump is connected between the built-in plate-type heat exchanger and the floor-heating manifold. The floor-heating manifold is connected with a first floor heating through a first floor-heating solenoid valve and connected with a second floor heating through a second floor-heating solenoid valve. The system has the advantages of reliable operation, safety and energy conservation.

Description

technical field [0001] The invention relates to an air-conditioning and hot water system, in particular to an air source modular three-in-one air-conditioning and hot water system. Background technique [0002] The air source modular three-in-one air-conditioning and hot water system is an air-conditioning system composed of air-conditioning and hot-water units. The air-conditioning and hot-water It can generate domestic hot water while cooling or heating, and can also generate domestic hot water when cooling or heating is not needed. However, the current air source modular three-in-one air-conditioning and hot water system has the following problems: [0003] 1. At present, the outdoor unit of the air-source air-conditioning unit is driven by the indoor unit, realizing one-to-one or one-to-multiple units. The air source and multi-connection can be combined, but not too many, the internal structure is complicated, the production process is complicated, and the maximum can o...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, the outdoor unit of the air-source air-conditioning unit is driven by the indoor unit, realizing one-to-one or one-to-multiple units. The air source and multi-connection can be combined, but not too many, the internal structure is complicated, the production process is complicated, and the maximum can only reach 48HP (horsepower) , the scale is limited, and multiple compressors are connected in parallel to form a system. After parallel connection, the system is complex and has many contacts. The refrigerant is easy to leak into a single room. The failure of a single compressor affects the operation of the air conditioning system and interferes with the power consumption of the air conditioning environment equipment. The refrigerant directly expands, and the indoor temperature fluctuates greatly during winter defrosting, which affects the comfort of the air conditioner

[0004] 2. At present, the traditional one-to-one household air conditioner adopts the first-generation capillary throttling. When the ambient temperature changes, the capillary refrigerant flow adjustment ability is very limited, and it cannot work normally under severe working conditions, and frequent defrosting in winter affects the air conditioner. The comfort of the system, and the fluorine system cannot store energy, and the compressor that starts and stops frequently during the temperature control process consumes more energy than the compressor that runs all the time

Without hot water function, heat is wasted in summer, and the energy consumption of air conditioner is higher

[0005] 3. At present, the traditional large-scale central air-conditioning system generally uses two or three units. The air-conditioning water system is a large system. When the screw compressor is working, it is in mechanical contact, with large vibration and high noise. Boiler, when the load drop is small, the efficiency is reduced, and the whole system must be put into operation when the local area is used, and the whole system cannot operate normally when there is a partial failure
