Abstract

Provided is a solar dehumidifying and cooling system including a solar hot water device that produces hot water by using solar heat and a dehumidifying and cooling device that performs cooling through heat exchange with the hot water that is supplied from the solar hot water device.

First claim

What is claimed is:

1. A solar dehumidifying and cooling system comprising:
a solar hot water device that produces hot water by using solar heat;
a hot water supply device coupled to the solar hot water device that supplies hot water;
a dehumidifying and cooling device that performs cooling through heat exchange with hot water supplied from the hot water supply device;
an auxiliary heat source coupled to the hot water supply device;
an external sensor; and
a controller which is
configured to control the auxiliary heat source,
configured to adjust a preset temperature of hot water from the hot water supply device in accordance to information from the external sensor corresponding to external air temperature and/or external air humidity, and
configured to adjust an amount of hot water to the solar dehumidifying and cooling device.

2. The solar dehumidifying and cooling system of claim 1 , wherein the solar humidifying and cooling device comprises:
a casing that comprises a partition wall formed therein;
a first channel and a second channel that are disposed in the casing, are divided by the partition wall, and allow air to flow therein;
a dehumidifying rotor that is provided on the partition wall and is disposed to extend over the first channel and the second channel;
a regenerator that is disposed to transfer heat to the air in the second channel; and
a cooler that cools the air in the first channel,
wherein the regenerator transfers the heat of the hot water that is supplied from the hot water supply device to the air in the second channel.

3. The solar dehumidifying and cooling system of claim 1 , wherein
the controller adjusts an amount of heat that is supplied to the auxiliary heat source.

4. The solar dehumidifying and cooling system of claim 1 , further comprising a flow meter coupled to the hot water supply device and coupled to the controller to detect a flow rate of hot water supplied to the regenerator.

5. The solar dehumidifying and cooling system of claim 2 , wherein the regenerator comprises a heating medium circulation circuit comprising a heating medium that receives heat through the heat exchange with hot water from the hot water supply device and transfers the heat through heat exchange with the air in the second channel.

6. A method of controlling a temperature of hot water that is supplied to a dehumidifying and cooling device, the method comprising:
collecting heat at a solar collector;
exchanging heat from the solar collector into a hot water supply device;
receiving information at a controller from an external sensor in which the received information corresponds to external air temperature and/or external air humidity from an external sensor;
adjusting a preset temperature with an auxiliary heat source in accordance to the received information at the controller;
heating hot water at the hot water supply device in accordance to the adjusted preset temperature; and
adjusting an amount of hot water flowing to the solar dehumidifying and cooling device.

7. The method of claim 6 , wherein when the temperature of the hot water in the hot water supply device is lower than the adjusted preset temperature then the controller controls an auxiliary heat source to increase the temperature of the hot water in the hot water supply device to the adjusted preset temperature.

8. A solar dehumidifying and cooling system comprising:
a solar collector;
a heat exchanger coupled to the solar collector;
a heat storage tank coupled to the heat exchanger;
an auxiliary heat source coupled to the heat storage tank;
a dehumidifying and cooling device that comprises:
a first channel and a second channel disposed in a casing and divided by a partition wall,
wherein the first channel comprises a cooler which dehumidifies and cools air,
wherein the second channel comprises a regenerator coupled to the heat storage tank, and a dehumidifying rotor that absorbs moisture from air;

an external sensor; and
a controller coupled to the external sensor and coupled to the heat storage tank, wherein the controller is
configured to control the auxiliary heat source,
configured to adjust a preset temperature of hot water from the heat storage tank in accordance to information from the external sensor corresponding to external air temperature and/or external air humidity, and
configured to adjust an amount of hot water to the solar dehumidifying and cooling device from the heat storage tank.

9. The solar dehumidifying and cooling system of claim 8 , further comprising a flow meter coupled to the regenerator.

10. The solar dehumidifying and cooling system of claim 8 , wherein the cooler is selected from the group consisting of a heat exchange rotor, a heat pump, and an evaporative cooler.
