Abstract

PURPOSE:To improve the heat exchange efficiency of an overall system by using both a heating system for water in a heating tank by means of the natural circulation action of refrigerant and a heating system for water in the heating tank by means of a freezing cycle. CONSTITUTION:Heat exchangers 4A, 5A make up a circulating hot water supply system in cooperation with a hot water reservoir tank 17. When the amount of sunshine is adequate, a heat collecting plate 1 is solely used as a heat source. When there is sunshine, the heat collecting plate 1 is heated, and the refrigerant such as flon gas in refrigerant pipe 2 in the heat collecting pipe 1 becomes high-temperature, high-pressure steam which enters the heat exchanger 4A to form a circulation loop of the refrigerant as shown by solid line arrows, and hot water at a suitable temperature is stored in the hot water reservoir tank 17. When the amount of sunshine is inadequate, the heat generated during the adiabatic compression process of the refrigerant by a compressor 14 is used in addition to the heat collecting plate 1. That is, as a preparatory process, a three-way valve 11 is switched and the compressor 14 is started to introduce the refrigerant liquid staying in the refrigerant pipe 2 into an expander 15 to gasify the same which is then drawn into the compressor 14. At the moment when there is no refrigerant liquid in the refrigerant pipe 2, a normal operating mode is assumed, and a freezing cycle by the heat exchanger 5A is completed.

However, with conventional solar water heaters, if there is insufficient sunlight or if sunlight alone does not provide enough heat, the temperature of the water in the hot water tank will not rise, and it will freeze in the winter. There was a risk. On the other hand, although air source heat pumps have been recognized for their usefulness as energy-saving devices, they require defrosting operations in winter to prevent freezing, and they use only electricity as the power source for the device. Because there is
Considering the current power situation, which calls for a peak cut in power consumption during the summer, this point also poses a problem. In addition, water heaters that use both a solar water heater and an air source heat pump have high equipment costs (and have problems with depreciation). The common structure is to have the tank integrated with the tank and place it on the roof of the house, which poses problems in terms of capital investment and construction, such as the need to reinforce the structure of the house to withstand this weight.

による冷凍サイクルが構成される。Hereinafter, a method of using the apparatus of the present invention having the above configuration will be explained. First, when the amount of sunlight is sufficient, that is, when the amount of heat received from sunlight alone is sufficient, only the heat collecting plate (1) is used as a heat source. In this case, the three-way switching valve (11) is switched to make the pipes (A) and (B) communicate with each other, and the first heat exchanger (4
The refrigerant pipe (4) constituting A) and the lower part of the refrigerant pipe (2) in the heat collecting plate (1) are directly communicated (.
) is closed. When sunlight hits the heat collecting plate (1) under the above conditions, the heat collecting plate (1) is heated and the fluorocarbon gas etc. inserted into the refrigerant pipe (2) inside the heat collecting plate is heated. Due to this heat, the refrigerant turns into high-temperature, high-pressure steam and is transferred to the first heat exchanger (4
8) Flow into the interior. In the first heat exchanger, the refrigerant vapor gives heat to the water in the heating tank (18) and condenses, and the liquefied refrigerant passes through the three-way switching valve (11) from the pipe line (A) side. It flows toward the path (B) side and returns to the lower part of the heat collecting plate (1). That is, a refrigerant circulation loop shown by the solid arrow in FIG. 1 is formed, and the hot water storage tank (17) connected to the heating tank (18)
) is stored with warm water heated to an appropriate temperature. Next, when the amount of sunlight is insufficient or when the amount of heat is insufficient with sunlight alone, the heat is generated during the adiabatic compression process of the refrigerant gas by the compressor (14) together with the heat collector plate (1) heated by sunlight as a heat source. Combined with thermal energy. In this case, first, as a preparation process, switch the three-way switching valve (11) to connect the pipes (B) and (C), close the solenoid valves (12) and (9), and then turn on the compressor (14). When activated, the refrigerant liquid accumulated in the refrigerant pipe (2) at the bottom of the heat collecting plate (1) is introduced into the expander (15), gasified, and sucked into the compressor (14). When there is no more refrigerant liquid in the refrigerant pipes (2) disposed within the heat collecting plate (1), the above preparation process is completed and a steady state of operation is entered. In other words, the solenoid valve (
12) and short-circuiting the expander (15),
The 20th heat exchanger (5A) indicated by the dotted arrow in Figure 1
A refrigeration cycle is constructed.

環時と同様に、適温に加熱された温湯が蓄えられる。In this state, the high-temperature, high-pressure refrigerant gas that has been adiabatically compressed by the compressor (14) flows into the refrigerant pipe (5) constituting the second heat exchanger B (5A), and passes through the refrigerant pipe. The water in the heating tank (18) is heated and condensed. This liquefied refrigerant flows into the expander (8) through the liquid receiver (7), and breaks vJ! inside the expander. After expansion, the heat collecting plate (1)
Return to the inner refrigerant pipe (2). The refrigerant in the refrigerant pipe (2) receives thermal energy from sunlight and evaporates, and the refrigerant in the refrigerant pipe (2)
from the lower end of the compressor (14) through the three-way switching valve (11), electric key valve (12) and accumulator (13).
), thus constructing a refrigeration cycle that also uses the second heat exchanger (58), and the heating tank (18)
Hot water heated to an appropriate temperature is stored in the hot water tank (17) connected to the hot water storage tank (17), as in the case of natural circulation of the refrigerant.

が蓄えられる。As is clear from the above explanation, in the present invention, the heat exchangers (48) and (5A) in the heating tank (18) are used separately during the natural circulation of the refrigerant and during the refrigeration cycle, respectively. Since separate refrigerant circulation loops are configured as shown by solid line arrows and dotted line arrows, heat exchange efficiency is particularly improved during the refrigeration cycle. In addition, the hot water storage tank (17), which is installed on the ground or on the floor while being connected to the heating tank (18), is kept at an appropriate temperature at all times, whether during the natural circulation of the refrigerant or during the refrigeration cycle. A predetermined amount of heated hot water is stored.

止機構である。When the operation in the refrigeration cycle is completed, the solenoid valve (9) is opened to return the refrigerant liquid in the liquid receiver (7) into the refrigerant pipe (2) disposed inside the heat collecting plate (1), The liquid receiver (
7) Leave the inside empty. Note that the check valve (not indicated by reference number (10)) is a check valve that, when the refrigerant gas is in a natural circulation state, allows the evaporated gas of the refrigerant to pass through the electromagnetic valve (9) and the expander (8) to perform a second heat exchange. This is a backflow prevention mechanism that prevents water from flowing into the container (5A).

ともできる。In the embodiment described above, the third heat exchanger (68) arranged in the heating tank (3) in series connection with the expander (15) functions as a fin tube. However, the usage status of the heat exchanger in the heating tank is different during natural circulation and during refrigeration cycle, and separate refrigerant circulation loops are configured as shown by the solid and dotted arrows. , it is possible to particularly improve heat exchange efficiency during the refrigeration cycle. Note that the third heat exchanger (6A) and the expander (15) in the above embodiment are members for preventing overload when the compressor (14) is started, and are not essential to the configuration of the present invention. do not have. Further, the compressor (14) and the liquid receiver (7) may be arranged within the heating tank (18), and by adopting such a structure, the thermal efficiency of the entire apparatus can be further improved. However, in order to reduce the weight of the heating tank (18), which is usually installed on the roof of the building, a heat exchanger (4A
), (5A) and (6A), the capacity of the heating tank (18) is preferably reduced as much as possible within a range that does not impede the heat exchange function of (5A) and (6A). On the other hand, the hot water storage tank (17) installed on the ground or on the floor needs to have a predetermined capacity suitable for the amount of hot water used under normal usage conditions. As mentioned above, the embodiments of the present invention have been described based on the example shown in FIG. For example, in order to reduce the pressure loss in the refrigerant pipes arranged in the heat collecting plate, the refrigerant pipes are constructed with a composite multi-tube structure consisting of a composite structure of two or more refrigerant pipes. In order to simplify the installation work, the heat collector plate, hot water storage tank, heat exchanger main body, and their attached devices are made separable, and these components can be assembled into an integrated structure at the construction site. Applications such as connecting to form a water heater can be included.Furthermore, the upper surface of the heat collecting plate is covered with a suitable cover member such as a glass plate,
It is also possible to improve the heat exchange efficiency during natural circulation of the refrigerant.

Effects of the Invention As is clear from the above explanation (according to the present invention, the hot water storage tank for storing hot water can be installed on the floor or the ground separately from the main body of the heat exchanger, There is no need to mount the entire submersible machine on top of the submersible, and an easy-to-use solar system-based water heater can be installed even in a general household where the strength of the building is relatively small. This water heater using a solar system uses both a system for raising the temperature of water in the heating tank through the natural circulation of the refrigerant and a system for raising the temperature of the water in the heating tank using a freezing cycle, thereby increasing the temperature of the entire device. The heat exchange efficiency can be greatly improved.Therefore, the present invention has excellent practical value as it provides a water heater using a solar system with a good energy saving effect.
