Abstract

A fluid distribution system for optimizing consumption of energy is provided comprising: a thermal controller configured to be connected to an external fluid tank containing external fluid having an external fluid temperature adapted to be heated by solar energy, and to an internal fluid tank containing an internal fluid having an internal fluid temperature and a heater adapted to be heated by a non-renewable energy, the thermal controller being configured to be connected to thermostats located at the internal and external tanks for determining the internal fluid temperature and the external fluid temperature; a valve in fluid communication with the internal and external tanks; a fluid controller connected to the thermal controller and to the valve, the fluid controller being configured to operate the valve based on the internal and external fluid temperatures in such a manner to optimize consumption of the non-renewable energy for heating the internal fluid.

First claim

The invention claimed is:

1. A fluid distribution system for optimising consumption of energy, the system comprising:
a thermal controller configured to be connected to an external fluid tank containing an external fluid having an external fluid temperature adapted to be heated by solar energy, and to an internal fluid tank containing an internal fluid having an internal fluid temperature and a heater adapted to be heated by a non-renewable energy, the thermal controller being configured to be connected to thermostats located at the internal and external tanks for determining the internal fluid temperature and the external fluid temperature;
a valve in fluid communication with the internal and external tanks;
a fluid controller connected to the thermal controller and to the valve, the fluid controller being configured to operate the valve based on the internal and external fluid temperatures in such a manner to optimise consumption of the non-renewable energy for heating the internal fluid;
a user interface connected to the thermal controller adapted to enable a user to indicate a desired fluid temperature for use and a time frame for obtaining a fluid with the desired temperature available for use;
a fluid volume meter for determining a volume of the internal fluid inside the internal fluid tank; and
a calculator connected to the thermal controller, to the user interface and to the fluid volume meter, wherein the calculator is configured to determine an optimal volume of the external fluid for mixing with the internal fluid as a function of first criteria comprising the internal and external fluid temperatures, the user desired fluid temperature, and the volume of the internal fluid inside the internal fluid tank in such a manner to optimize consumption of the non-renewable energy for heating the internal fluid;
wherein the calculator is connected to the fluid controller for controlling the valve for enabling flow of the determined optimal volume of external fluid inside the internal tank for mixing with the internal fluid and obtaining a mixed fluid having a mixed fluid temperature; and
wherein the calculator is configured to determine the optimal volume of fluid to obtain from the external fluid tank and the optimal volume of fluid to obtain from the internal tank for mixing and an amount of time required for heating the mixed fluid as a function of second criteria comprising the internal and external fluid temperatures, the user desired temperature and time frame specified by the user for obtaining the mixed fluid with the desired temperature available for use.

2. The system as claimed in claim 1 , further comprising a buffer tank in fluid communication with the external and internal tanks and the valve and wherein the calculator further determines whether it is beneficial to use the buffer tank to mix the internal and external fluids and heat up the mixed fluid obtained rather than using the internal tank, wherein the determination is made as a function of the second criteria in addition to the volume of the internal fluid and a volume capacity of the internal tank.

3. The system as claimed in claim 1 , further comprising a solar thermal system in thermal communication with the external tank for heating the external fluid.

4. The system as claimed in claim 1 , wherein the internal fluid and the external fluid is water.
