JPS60149850A - Heat pump type hot water supplier utilizing solar heat - Google Patents

Abstract

PURPOSE:To provide the titled heat pump type hot water supplier improving the operational efficiency and being sufficiently put to practical uses even in a cold district by forming one surface of the main body of the supplier by a transparent member, causing a blower to face a vent port and providing a shutter capable of opening or closing the vent port. CONSTITUTION:A heat pump device is incorporated within the main body 11. The hot water supplier is constituted so that solar heat 27 is effectively received on the front surface provided with a transparent member 12 of the main body 11. When the solar heat 27 is being obtained, the blower 23 is stopped to operate, and the shutter 24 is closed. Then, the temperature within the main body 11 rises up by a greehouse effect. Hence, a sufficient heat quantity can be secured by an evaporator 19. Further, the heat collecting efficiency is improved by irregular reflection at the part of fins 192. Accordingly, even when the temperature of external air is low, the operational efficiency is not lowered. Further, when the solar light cannot be used, that is, at night-time, for example, the shutter 24 is opened, and the blower 23 is operated, thus absorbing the heat quantity possessed by the external air.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for producing hot water using condensation heat of a heat pump device, that is, a heat pump type water heater.

Since a heat pump device releases heat absorbed in an evaporator in a condenser, if heat absorption in the evaporator is insufficient, sufficient heat radiation cannot be obtained in the condenser. Conventionally, in a heat pump device, the heat absorption in the evaporator depends only on the outside air, so when the temperature of the outside air is low, heat absorption may be insufficient, leading to a decrease in operating efficiency.

Therefore, heat pump water heaters are considered unsuitable for cold areas.

In view of the above, an object of the present invention is to improve the operating efficiency of a heat 1.1e pump 0 water heater.

Another object of the present invention is to provide a heat pump water heater that can be put to practical use even in cold regions.

Examples will be described below with reference to the drawings.

Referring to FIGS. 1 to 3, the water heater shown in FIG. 1 includes a substantially vertically elongated rectangular parallelepiped-shaped box or body 1f. The main body 11 has a transparent body 12 on the front side. A heat insulating tank 13 is provided at the rear of the main body 11 .

The heat insulating tank 13 has a heat insulating material 133 interposed between the tank interior plate 31 and the tank exterior plate 132.

A tap water supply pipe 14 is provided at a relatively lower portion of the heat insulating tank 13, and a hot water outlet pipe 15 is provided at a relatively upper portion.

A heat pump device is also incorporated inside the main body 11. This heat 2 knob device consists of a compressor 16, a condenser 1
7. 1, 8, an evaporator 19 and a refrigerant circuit with the necessary connections and connections (eg 21). The condenser 17 is.

It has a cylindrical coil shape and is positioned at the inner bottom of the heat insulating tank 13. On the other hand, the evaporator 19 has an eccentric X-shape in which a meandering pipe 191, which serves as a refrigerant passage, is combined with a large number of fins 192 to enhance the heat collection effect. , the upper part is positioned at an angle to the rear. Note 2
2 is a reservoir for the evaporator (=1 piece).

Further, a ventilation port 111 is formed on the upper surface of the main body 11, a blower 23 is made to correspond to the ventilation port 111, and a connector 24 that can open and close one ventilation port 111 is provided. Further, ventilation outlets 112 are provided on the front and side surfaces of the lower part of the main body 11. The air thus sucked in by the blower 23 flows through the fins 192 of the evaporator 19, as shown by the dashed arrow 25 in FIG.
Turn on the water and operate the heat pump device.

The heat absorbed by the evaporator 19 condenses 5! The i-container 17 is also discharged, raising the water temperature in the heat insulating tank 13. Hot water 26 in the insulated tank 13 can be taken out from the hot water take-off pipe 15.

This heat pump water heater is installed so as to effectively receive sunlight 27 on the front surface of a main body 11 provided with a transparent body 12. When sunlight 27 is available, the blower 23 is stopped and the 7-ray fan 24 is closed. Then, the temperature inside the main body 1 increases due to the greenhouse effect, so that the evaporator 19 can secure a sufficient amount of heat. More fi :/
Diffuse reflection at the 192 portion also improves heat collection efficiency. Therefore, even if the outside temperature is low, there is no reduction in operating efficiency. Also, when sunlight cannot be used (1), for example at night, the shutter 24 is opened and the blower 23 is operated.
It is better to absorb the amount of heat that the outside air has. You can do it automatically,
This may be done automatically based on the internal pressure of the evaporator 19.

It is preferable that the blower 2; 3 and the blower 24 are configured to interlock with each other.

As explained above using the embodiments, according to the present invention,
Since energy from outside air and energy from sunlight can be used selectively, it is possible to provide heat pump water heaters with improved operating efficiency. In addition, since this water heater has a heat pump device and an insulated tank in one body, it is relatively easy to change its posture and orientation, so it can be installed to receive sunlight more effectively. It's convenient.
