Water-cooling multi-connecting type heat recovery floor heating hot-water system for air conditioner

Abstract

The invention relates to the technical field of air conditioner equipment, in particular to a water-cooling multi-connecting type heat recovery air conditioner floor heating hot-water system. The system comprises an indoor unit, an outdoor unit, a domestic hot water system arranged separately and a floor heating hot-water system. Compared with the prior art, the water-cooling multi-connecting type heat recovery air conditioner floor heating hot-water system has the advantages that floor heating hot water and domestic hot water are disposed separately, safety of water quality of domestic hot water is guaranteed, comprehensive energy efficiency is high, the system is more energy-saving, and the problem of low efficiency caused by retention of refrigerating fluid in the indoor unit to lead to insufficient refrigerating fluid recycling in the system when the indoor unit is operated in the closed state is solved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a water-cooled multi-connected heat recovery air-conditioning floor heating and hot water system. Background technique [0002] In the prior art, the floor heating and hot water system of the water-cooled multi-connected air conditioner treats the floor heating and domestic hot water together, and then supplies the floor heating and hot water tanks separately. This method has the following defects: 1) Due to the 2) Treat the ground heating water and the hot water tank together. According to the operating range of the conventional compressor, the temperature of the outlet water is bound to be lower, generally lower than 50°C. Then it will reach the hot water tank. If the water temperature is less than 50°C, when the user needs a higher water temperature, electric heating is required to meet it, resulting in low energy efficiency and waste of energy; 3) When the ...

[0002] In the prior art, the floor heating and hot water system of the water-cooled multi-connected air conditioner treats the floor heating and domestic hot water together, and then supplies the floor heating and hot water tanks separately. This method has the following defects: 1) Due to the 2) Treat the ground heating water and the hot water tank together. According to the operating range of the conventional compressor, the temperature of the outlet water is bound to be lower, generally lower than 50°C. Then it will reach the hot water tank. If the water temperature is less than 50°C, when the user needs a higher water temperature, electric heating is required to meet it, resulting in low energy efficiency and waste of energy; 3) When the indoor unit of the system is in the off mode, the refrigerant stays In the indoor unit, the problem of insufficient capacity and reduced efficiency caused by insufficient refrigerant circulation in the system is often required to add solenoid valves on both sides of each indoor unit to solve this problem.
