Abstract

PURPOSE:To reduce cost and to improve the economical efficiency of the titled hot water supplying device more than the conventional one requiring an additional auxiliary heat source by a method wherein in the case of the hot water supplying device using a heat pump as a solar heat collecting means, a plurality of auxiliary heaters are provided in a hot water storage tank. CONSTITUTION:In case where the atmospheric temperature is high, a coolant compressor 2 and a water circulation pump 6 are operated by an open air temperature thermostat 13 and feed hot water in the hot water storage tank 5 is transferred to a water heater 7 so as to be heated by the heat of condensation of the coolant. Thus, when a secondary hot water thermostat 11 reaches a set temperature, the operations of the coolant compressor 2 and the water circulation pump 6 are stopped. Further, in the case where the open air temperature is low, the heating operation is actuated by a secondary auxiliary heater 12 due to the action of the open air temperature thermostat 13 to thereby secure the calorific value of the hot water. With the above structure, a certain quantity of the hot water at the upper part of the hot water storage tank is always heated to a predetermied temperature by a first hot water thermostat 9 and a first auxiliary heater 10 provided at the upper part of the tank 5 so that the hot water feeder can meet a hot water feeding load in the early morning and no shortage of hot water takes place.

In order to solve all of the drawbacks of conventional solar heat collectors, we are proposing a heat collector that uses a heat pump as a means of collecting solar heat. That is, as shown in FIG. 1, a heat collecting plate 1 consisting of a fin-tube heat exchanger, a refrigerant compressor 2. Condenser 3
.. Expansion valves 4 are sequentially connected in a ring to form a refrigerant heat collection circuit, and a hot water storage tank 6. Water circulation bonder6. A water heating circuit is formed by connecting a 7ft water heater in a ring, and the condenser 3 of the refrigerant heat collection circuit and the water heater 7 of the water heating circuit are held in a heat transfer relationship to form a heat collection device.

High pressure refrigerant gas flows into the condenser 3. The discharged refrigerant gas that has flowed into the condenser 3 radiates heat to the hot water flowing through the water heater A, which is in a heat transfer relationship, and after being condensed and liquefied, reaches the expansion valve 4.
When passing through the expansion valve 4, the refrigerant expands adiabatically and is depressurized to become a low-temperature, low-pressure unevaporated refrigerant, which flows into the heat collector 1. Here the low temperature
The low-pressure unevaporated refrigerant absorbs heat from the sun and the atmosphere, becomes evaporated and gasified, flows out of the heat collector 1, and is sucked into the compressor 2 again, repeating the cycle. On the other hand, the hot water in the needle tank 6 is sent to the water heater 7 by the action of the water circulation pump 6.
The water is heated by the heat of condensation of the refrigerant in the water heater 7 to raise its temperature, and then flows back into the hot water storage tank 5 again.

As described above, by using a heat pump as a means for collecting solar heat, low-temperature heat collection is performed, so that heat collection efficiency is improved. Furthermore, since it is possible to collect heat even on rainy or cloudy days when there is no sunlight, the amount of heat collected can be increased. However, when the outside temperature drops in winter, the heat collector 1 may adhere to the surface of the heat collector 1, and the heat collecting operation may not be possible. For this reason, an auxiliary heat source 8 must be connected to the outlet of the hot water storage tank 6. In other words, most of the hot water supply load can be handled by the amount of heat collected by the heat pump, but a large auxiliary heat source must be provided for the slight shortage of heat, which reduces running costs but increases equipment costs. remains.
