Water self-circulation heat-exchange type refrigerating, heating and water heating three-purpose machine

Abstract

The invention discloses a water self-circulation heat-exchange type refrigerating, heating and water heating three-purpose machine. The water self-circulation heat-exchange type refrigerating, heating and water heating three-purpose machine is characterized in that a refrigerant circulation loop is additionally provided with a heat storage and heat exchange integrated water tank and four one-way valves, the heat storage and heat exchange integrated water tank is provided with two heat exchanger coils, and then two one-way running water heat exchanger assemblies are formed by the heat storage and heat exchange integrated water tank and the four one-way valves; a heat pump circulation loop is from a compressor to a four-way valve to the first heat exchanger coil to a first one-way valve to an indoor air heat exchanger to a throttle to an outdoor air heat exchanger to a fourth one-way valve to the four-way valve to a gas-liquid separator to the compressor; a refrigeration circulation loop is from the compressor to the four-way valve to the second heat exchanger coil to a third one-way valve to the outdoor air heat exchanger to the throttle to the indoor air heat exchanger to a second one-way valve to the four-way valve to the gas-liquid separator to the compressor; and the top of a cylinder type water heat exchanger assembly is connected with the top of a hot water storage tank through a water pipe, the bottom of the cylinder type water heat exchanger assembly is connected with the bottom of the hot water storage tank through a water pipe, and a water self-circulation loop is formed by water channels. According to the water self-circulation heat-exchange type refrigerating, heating and water heating three-purpose machine, through control over starting and stopping of an indoor draught fan and an outdoor draught fan and switching of the four-way valve, the four functions of generating hot air, generating hot water, generating cool air and serving as both an air conditioner and a water heater can be achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning / heat pump heating and hot water systems. Background technique [0002] With the improvement of people's living standards, while meeting the needs of indoor heating, air conditioning and hot water supply, energy saving and low-carbon environmental protection are also required as much as possible. The multi-functional heat pump water heater unit is the most suitable equipment and is also the most popular research topic at present. , There are also many patents, including the applicant who has also applied for and been authorized many patents on multifunctional hot water heat pumps, but because the refrigerant is a multi-circuit system, manufacturers still encounter difficulties in the production process. In the current cold and warm water fans, the refrigerant circulates between the air heat exchanger and the water-cooled heat exchanger, and the direction of the refrigerant circulation is s...

Problems solved by technology

[0003] In order to overcome the disadvantages of complex refrigerant loops of the existing multifunctional heating and air conditioning hot water heat pumps, retain the advantages of the existing cold water air conditioners with simple structure and refrigerant circulation in a single loop, and make up for the inability to organize refrigeration and air conditioning while producing hot water for bathing, To make better use of the energy-saving effect of the heat pump, the present invention proposes a water self-circulating heat exchange type cold, warm and hot water three-purpose machine. By improving the refrigerant circulation system of the cold water air conditioner, it can perform heating heating in winter and air conditioning in summer. Simultaneous production of hot water for bathing, separate air conditioning and cooling, and four operating modes for separate production of bathing hot water throughout the year, so as to achieve the three-purpose purpose of heating, air conditioning and bathing hot water
