Hot-water air conditioner

Abstract

The present invention provides a hot water air-conditioner, which comprises an indoor unit and an outdoor unit of the air-conditioner, and is characterized in that an outlet of a compressor arranged on the outdoor unit is connected with a functional steering valve. An outlet of one side the functional steering valve is connected with an inlet of a water condenser, and an outlet of the other side is connected with the import of a cold-warm steering valve. The outlet of the water condenser is in series connected with a filter and end a of a three-terminal electronic throttling valve. An outlet of one side of the cold-warm steering valve is connected with one end of the indoor unit. The middle port of the cold-warm steering valve is connected with an air returning opening of the compressor. An outlet of the other side of the cold-warm steering valve is connected with one end of an outdoor heat exchanger. The other end of the outdoor heat exchanger is connected with end b of the three-terminal electronic throttling valve. The other end of the indoor unit is connected with end c of the three-terminal electronic throttling valve. A micro motor connection with a valve core is arranged inside the three-terminal electronic throttling valve. The present invention has the advantages of easy achievement of production of cooling and hot water by the simple structure, free switching of the functions of the hot water of a heat pump, single production of cold air and single production of warming air, etc. The best efficiency is guaranteed by the automatic regulation of the liquid supplying quantity of the refrigerant under the working mode of single production of the cold air or the single production of the warming air. The present invention also has excellent operation after being applied on a central air conditioning unit.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a hot water air conditioner capable of producing hot water. Background technique [0002] The current air conditioners all discharge the heat generated by indoor cooling to the outside, and at the same time, the hot water required by households or public places is produced by electricity or gas, resulting in a double waste of energy expenditure. Although I once proposed a patent for simple and reliable hot water heating of an air conditioner, due to the application of this invention, it must be ensured that the exhaust pipes of the indoor heat exchanger and the outdoor heat exchanger must be in a forward flow, otherwise, in the refrigeration / Hot water, heat pump hot water work, there will be a small amount of uncondensed gas into the evaporator, greatly reducing the system efficiency, and the current small household air conditioners in order to improve cooling and heating efficiency, the in...

[0002] The current air conditioners discharge the heat generated by indoor cooling to the outside, and at the same time, the hot water needed in homes or public places is produced by electricity or gas, resulting in a double waste of energy expenditure.

Although I once proposed a patent for simple and reliable hot water heating of an air conditioner, due to the application of this invention, it must be ensured that the exhaust pipes of the indoor heat exchanger and the outdoor heat exchanger must be in a forward flow, otherwise, in the refrigeration / Hot water, heat pump hot water work, there will be a small amount of uncondensed gas into the evaporator, greatly reducing the system efficiency, and the current small household air conditioners in order to improve cooling and heating efficiency, the indoor unit heat exchanger, the outdoor unit is replaced The heater is designed to be interspersed and circulated up and down. Therefore, the original patent for the hot water air conditioner is not suitable for the modification and continuation of the design and production of the existing air conditioner.
