Abstract

PURPOSE:To simplify the constitution of the captioned device by a constitution wherein the evaporating section of a heat collector is communicated with the inside of a heat radiator through a pressure increase valve while a liquid receiver, provided above the liquid reservoir of the heat collector, is communicated with the liquid reservoir of the heat radiator, in the captioned device in which heat is transferred from the upper part to the lower part thereof. CONSTITUTION:The pressure increasing valve 6 is closed to collect solar heat into the heat collector 1 and evaporate refrigerant 9. When the temperature in the heat collector 1 is increased and the pressure goes above a given value, a pressure switch 17 is operated to open the pressure increasing valve 6. Accordingly to this operation, the high-pressure evaporated refrigerant 9 in the heat collector 1 is flowed into the radiator 2. The refrigerant 9, dissipating the heat thereof in the radiator 2 and condensed, is pushed up to the liquid receiver 3 by the pressure of evaporated refrigerant in the radiator 2. When the pressures in systems 1-3 are balanced and the pressure switch 16 is operated, the valve 15 is opened and the refrigerant 9 in the liquid receiver 3 is flowed into the liquid reservoir 4. According to this constitution, the constitution of the captioned device may be simplified.

[For production]

When the pressure increase valve is closed and heat is collected in the collector, the temperature inside the collector rises, and as the refrigerant evaporates, the pressure inside the collector increases, and when the pressure increase valve is opened at a predetermined time, the heat collector The internal high-pressure vaporized refrigerant flows into the radiator, and the radiator emits heat to the outside, and the refrigerant condenses and liquefies. This liquefied refrigerant is pushed up into the liquid receiver by the pressure of the high-pressure vaporized refrigerant, and The liquefied refrigerant inside the container shall be stored in the liquid reservoir of the heat collector.

〔Example〕

Figure 1.2 shows an example in which the present invention is used for heating underground water, where (1) is a heat collector that receives sunlight, and (2)
is a radiator buried underground, and radiator (2) is a heat collector ti
Below + (2 installed.

(3) is a liquid receiver, in this case formed of a heat insulating member, and provided above the liquid reservoir (4) of the heat collector (1).

The evaporation part (5) of the heat collector (1) and the inside of the heat radiation part (2) are communicated with each other by a steam pipe (7) via a pressure increase valve (6),
The inside of the radiator (2) and the liquid receiver (3) are the liquid pipe (8)
The interior of the liquid receiver (3) and the liquid reservoir (4) of the heat collector (1) are connected to each other by (3) the refrigerant (9) flowing only from the liquid receiver (3) to the heat collector (1). ) is communicated with the civil code pipe 0]) through a check valve 0Q that allows the flow of water.

In addition, in this embodiment, the liquid receiver (3) and the radiator (2) are connected to each other via a check valve that allows gas to flow only in the direction from the liquid receiver (3) to the radiator (2). (3) and the radiator (2) A pressure equalizing pipe (1~ communicates with each other to keep the pressure inside the radiator constant)
In addition, the evaporation part (5) of the heat collecting pipe (1) and the liquid receiver (3) are communicated through a pressure equalizing pipe Q41, and an on-off valve is interposed in the middle thereof,
A differential pressure switch (16) is provided in parallel with the on-off valve a1, and a pressure switch (0T) is installed on the evaporation section (5) side of the pressure equalization pipe (04).

α~ is a safety valve.

Since this embodiment has the above configuration, when the pressure increase valve (6) is closed and heat is collected from sunlight by the heat collector (1), the heat collector tl
The temperature inside j rises, the refrigerant (9) in the heat collector (1) evaporates, and the temperature rises inside the heat collector (1).If this pressure exceeds a certain level, in this case, the pressure will rise, Te07) is activated, which causes the pressure increase valve (6) to open, and the high-pressure vaporized refrigerant (9) inside the collector (1) flows into the radiator (2), and the radiator (2) releases it to the outside. In this case, the ground water is released, and the refrigerant (9) is condensed and liquefied, and this liquefied refrigerant (9) is
) is pushed up into the receiver (3) by the high pressure of the vaporized refrigerant (9) in the radiator (2).

When the pressure inside the heat collector tl), the heat radiator (2), and the liquid receiver (3) reach an equilibrium (same) state, the differential pressure
Q is activated, the on-off valve α■ opens, and the refrigerant (9) in the liquid receiver (3) smoothly flows into the liquid reservoir (4) of the heat collector tl).

Then, when a predetermined period of time has elapsed after the differential pressure switch QEil was activated, a timer activates the pressure increase valve (6) and b.
The first closing valve αω is closed, returning to the original state, and the heat transfer cycle is repeated again.

Therefore, underground water can be warmed by the heat of sunlight, and there is no need to pump up the liquefied refrigerant in the radiator (2), eliminating the need for a pump, simplifying the piping circuit configuration, and reducing costs. becomes.

In addition, the closing operation of the pressure increase valve (6) and the on-off valve αω is as follows:
This can also be done by detecting with a sensor that the pressure in the heat collector (1) has started to rise.

As described above, the present invention eliminates the need to pump up the liquefied refrigerant in the radiator below the heat collector by appropriate means, and therefore allows heat to be easily transferred from above to below, and the conduit structure is simple. can be expected to reduce costs.

As described above, the intended purpose can be fully achieved.
