Embodiment approach 1

[0036] figure 1 It is a refrigerant circuit diagram showing the refrigerant circuit configuration (refrigerant circuit configuration during cooling main (cooling+hot water supply) operation) of the combined air-conditioning and hot water supply system 100 according to Embodiment 1 of the present invention. according to figure 1 , to describe the refrigerant circuit structure of the combined air-conditioning and hot water supply system 100 , especially the refrigerant circuit structure during the main cooling (cooling + hot water supply) operation. This combined air-conditioning and hot-water supply system 100 is installed in buildings, apartments, etc., and can simultaneously provide air-conditioning (cooling or heating) and hot-water supply by forming a refrigeration cycle (heat pump cycle) that circulates an air-conditioning refrigerant. Additionally, include figure 1 In addition, in the following drawings, the relationship of the size of each component may differ from the...

Embodiment approach 2

[0104] Figure 7 It is a refrigerant circuit diagram showing the refrigerant circuit structure (particularly, the refrigerant circuit structure during cooling main (cooling + hot water supply) operation) of the combined air-conditioning and hot water supply system 100a according to Embodiment 2 of the present invention. according to Figure 7 The refrigerant circuit structure of the combined air-conditioning and hot water supply system 100a will be described. This combined air-conditioning and hot-water supply system 100a is installed in a building, an apartment, etc., and can simultaneously provide air-conditioning (cooling or heating) and hot-water supply by utilizing a refrigeration cycle that circulates a refrigerant (refrigerant for air-conditioning). In this second embodiment, differences from the above-mentioned first embodiment will be mainly described, and the same parts as those in the first embodiment will be given the same reference numerals, and their description...

Embodiment approach 3

[0145] Figure 13 It is a configuration diagram of an air-conditioning and hot water supply combined system 100b according to Embodiment 3 of the present invention. This third embodiment will be described focusing on the points of difference from the above-mentioned first embodiment, and the same parts as those in the first embodiment will be assigned the same reference numerals, and their description will be omitted.

[0146] in the Figure 13 , the solid line indicates the state of the four-way valve 102 in the cooling main (cooling + hot water supply) operation and the heating main (cooling + hot water supply) operation, and the dotted line indicates the full heating (heating + hot water supply) operation The state of the four-way valve 102 in. Such as Figure 13 As shown, the combined air-conditioning and hot water supply system 100b of the third embodiment is basically the same as the combined system 100 for the air-conditioning and hot water supply of the first embodi...

Abstract

A combined system of an air conditioning device and a hot-water supply device, the system being provided with: an air conditioning refrigeration cycle comprising a heat source unit (A), an indoor unit (B), a hot-water supply heat source circuit (D) provided with a refrigerant-to-refrigerant heat exchanger (41) and a flow restriction means (119) for a hot water supply heat source, and a branch unit (C) for dividing a refrigerant flowing to the indoor unit and the hot-water supply heat source circuit, the indoor unit and the hot-water supply heat source circuit being connected parallel to each other, the air conditioning refrigeration cycle being connected, using at least two lengths of connection piping (106, 107), to the heat source unit through the branch unit; and a hot-water supplying refrigeration cycle formed by connecting in series a hot-water supplying compressor, a heat medium-to-refrigerant heat exchanger, a flow restriction means for hot water supply, and the refrigerant-to-refrigerant heat exchanger. The air conditioning refrigeration cycle and the hot-water supplying refrigeration cycle are connected in such a manner that an air conditioning refrigerant and a hot-water supplying refrigerant are subjected to heat exchange by the refrigerant-to-refrigerant heat exchanger.

Description

technical field [0001] The present invention relates to an air-conditioning and hot water supply composite system, which is equipped with a heat pump cycle, and can provide air conditioning (cooling or heating) and hot water supply at the same time, especially relates to the ability to meet the needs of high-temperature hot water supply, and Energy-saving air-conditioning and hot water supply composite system. Background technique [0002] Conventionally, there has been an air-conditioning and hot-water supply combined system capable of simultaneously providing high-temperature hot water supply and indoor air-conditioning through a dual refrigeration cycle. As such a composite system, "a heat pump hot water supply device having a low-stage refrigerant circuit, a high-stage refrigerant circuit, and a hot water supply path; The refrigerant circuit connects these devices in the order of the first compressor, refrigerant distribution device, first heat exchanger, second heat ex...
