Embodiment approach 1

[0047] according to Figure 1 ~ Figure 3 , the heat pump hot water heater according to Embodiment 1 of the present invention will be described.

[0048] figure 1 It is a configuration diagram of the heat pump hot water heater 1 which is the object of the present invention. The heat pump hot water heater 1 is composed of a heat pump cycle 2 , a hot water circulation circuit 8 and a control unit 16 .

[0049] The heat pump cycle 2 includes: a compressor 3 that sucks in refrigerant for compression and discharges high-temperature and high-pressure refrigerant; an air heat exchanger 4 that collects heat from outdoor air; Refrigerant fan 5; Refrigerant flow regulating valve 6 for adjusting the flow of refrigerant; and Water-refrigerant heat exchanger 7 for heat exchange between refrigerant and hot water.

[0050] On the other hand, the hot water circulation circuit 8 includes: a hot water circulation pump 9 connected to the water refrigerant heat exchanger 7 to circulate the hot ...

Abstract

A heat pump hydronic heater of the present invention includes: a heat pump cycle 2 comprising a compressor 3 and heating hot water; a plurality of radiating means 13a to 13c; a hot water circulation pump 9 circulating hot water heated by the heat pump cycle 2 to the plurality of radiating means 13a to 13c; opening / closing means 11a to 11d connected with the plurality of radiating means 13a to 13c; and a control section 16, characterized in that when set temperatures of the plurality of radiating means 13a to 13c are different from each other, the opening / closing means 11a to 11d which is connected to the radiating means 13a to 13c other than that 13a to 13c having the highest set temperature is opened and closed with a predetermined period, and closing timings of the plurality of opening / closing means 11a to 11d are set substantially the same. Floor heating panels of a plurality of rooms are operated at different floor temperatures, thereby enhancing comfort.

Description

technical field [0001] The present invention relates to a heat pump type hot water heater for heating with hot water generated using a heat pump. Background technique [0002] At present, most heating equipment uses combustion fuel such as oil or natural gas as a heat source, and the heating market using heat pump technology has rapidly expanded in recent years. [0003] However, only conventional air conditioners have the problem that the feet are difficult to warm during heating. In order to solve this problem, a hot water heater using heat pump technology is being developed (for example, refer to Patent Document 1). [0004] The hot water heating device described in Patent Document 1 performs heat exchange between a high-temperature refrigerant and hot water, and sends the heated hot water after the heat exchange to a heating terminal such as a floor heating panel for heating. [0005] In addition, the heat pump type hot water heater is configured by combining a refriger...
