Embodiment approach 1

[0019] [Structure of Embodiment 1]

[0020] figure 1 It is a circuit configuration diagram of the heating and hot water supply system 100 according to Embodiment 1 of the present invention. figure 1 The shown heating and hot water supply system 100 includes: a heat pump unit 1 equipped with a refrigerant circuit of a vapor compression refrigeration cycle (heat pump cycle); The water storage tank unit 10; and the heating unit 30 which is constituted by a part of the heating circulation circuit and heats the room.

[0021] The heat pump unit 1 and the hot water storage tank unit 10 are connected via heat medium pipes 12 and 13 . The hot water storage tank unit 10 is connected to the heating unit 30 via heat medium pipes 14 and 15 . In addition, the hot water storage tank unit 10 is connected to a hot water supply pipe 17 connected to a hot water supply terminal (such as a faucet in a kitchen or a toilet) and a water supply pipe 16 for supplying water from a water source such ...

Abstract

The invention provides a system for heating and supplying hot water, which can realize the requirements for supplying hot water and heating at the same time. The heating and hot water supply system includes: a heat pump unit (1) for heating the heat medium; a hot water supply heat exchanger (19) for performing heat exchange between the heat medium and the water in the hot water storage tank (11); Heating heat exchangers (31, 32) for heating the room with heat medium; heat medium pump (18); pump discharge side, heat pump unit, hot water supply heat exchanger, heating heat exchanger, and pump suction side The heating medium piping (12-15) connected in sequence; the bypass piping (22) bypassing the hot water supply heat exchanger from the heating medium piping; the bypass piping (23) bypassing the heating heat exchanger from the heating medium piping; A four-way valve (20) for adjusting flow distribution of heat medium between the hot water supply heat exchanger and the piping, and between the heating heat exchanger and the piping; and a control device (29) for controlling the four-way valves.

Description

technical field [0001] The present invention relates to a heating and hot water supply system, and in particular to a heating and hot water supply system that uses hot water heated by a heat pump as a medium to implement hot water supply and heating. Background technique [0002] Conventionally, for example, Patent Document 1 discloses a heating and hot water supply system, which has a heating system that realizes the heating function by circulating hot water heated by a heating mechanism to a heating terminal, A hot water supply system that heats the water in the hot water storage tank by circulating water to the heat exchanger in the hot water storage tank. Specifically, this heating and hot water supply system includes a circuit for circulating hot water heated by a heat pump unit to a heating terminal, and a circuit for circulating hot water to a heat exchanger in a hot water storage tank by using the heating terminal as a bypass. By switching the three-way valve provid...
