Dual-purpose machine for hot water and air conditioning

Abstract

The dual-purpose machine for hot water and air conditioning of the present invention comprises a thermal insulation water tank, an outdoor switchboard and at least one indoor switchboard, and a medium liquid circuit and a water liquid circuit are circulated in the outdoor switchboard; each indoor switchboard is connected with the water liquid circuit; The water tank has a built-in hot water exchanger, and the hot water exchanger is connected with the pipeline of the medium liquid circuit, and the body of the heat preservation water tank is connected with the pipeline of the water liquid circuit; the indoor waste heat is used to heat the domestic water, which saves energy while reducing Waste heat discharge; in winter, the heating method of hot water circulation should be used to increase the heating power consumption. The heating power consumption ratio of this technology can reach 230%, which significantly reduces energy consumption; the cold and hot water circulation is used to realize the control of indoor air temperature Adjustment, so one outdoor unit can adjust the indoor temperature of several rooms at the same time, which overcomes the deficiency of one air conditioner for one room in the traditional way, and saves installation space; the medium liquid adopts a closed operation mode, without environmental pollution.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a hot water and air conditioner with dual functions of providing domestic hot water and regulating indoor air temperature. Background technique [0002] The existing public air conditioners focus on refrigeration, and the heating in winter mainly relies on electric heating with low thermal efficiency and high energy consumption, and a large amount of waste heat in the exchange is discharged into the atmosphere. high. [0003] The existing public heat pump water heaters can only provide single hot water for daily life. This type of water heater only needs 1 / 4 of the winter operating power in summer, and only 1 / 2 of the winter operating power in spring and autumn. Three seasons a year Failure to operate at full load is a waste of equipment and also affects the balanced operation of the power supply network. [0004] At present, there is also a heat pump system with d...

[0002] The existing public air conditioners focus on refrigeration, and the heating in winter mainly relies on electric heating with low thermal efficiency and high energy consumption, and a large amount of waste heat in the exchange is discharged into the atmosphere. high

[0003] The existing public heat pump water heaters can only provide single hot water for daily life. This type of water heater only needs 1 / 4 of the winter operating power in summer, and only 1 / 2 of the winter operating power in spring and autumn. Three seasons a year Cannot run at full load, which is a waste of equipment and also affects the balanced operation of the power supply network

[0004] At present, there is also a heat pump system with dual functions of providing domestic hot water and regulating indoor air temperature, such as the Chinese utility model patent "High-efficiency heat pump system for hot water heating and air conditioning" (announcement) with the patent number ZL02820196.5 No. is CN1568417Y) is exactly this design; This system includes compressor, heat exchanger and hot water tank; This design adopts the exchange of pure water medium and air energy, and its efficiency is low, and water heating rate is slower; And lack of water An effective way to dissipate heat when the medium cools down, and the cooling effect on the indoor air temperature is not obvious; if it is necessary to provide hot water and cool the indoor temperature with higher efficiency, it needs to supplement more power resources, which consumes a lot of energy. Conducive to energy saving
