Technical field
The present invention relates generally to system, device and method for heating water.More particularly it relates to using too
Sun can heat the water source of receiving or provide system, device and the method for supplementary heating device for the water source of receiving.
Background technology
Heat recovery units (HRU) are well known in the art for collecting from the refrigeration cycle in air-conditioning system or heat pump system
The equipment of the waste heat of discharge.Mounted on (on air-conditioning) between compressor and condenser or mounted on (heat pump system) condenser
The HRU in refrigerant hot gas line between reversal valve will be in the heat transmission to boiler of collection.To realize this transmission,
The water end (W.E.) of HRU is connect in circulation loop with boiler, cold feed line entry flow.By entering water tank in cold feed
A part for cold feed is heated before, and HRU reduces the energy that water tank itself is consumed during heating water.Due to cold sky
Gas or steam leave the refrigeration end of HRU, so the unit also improves the cooling efficiency of air-conditioning system or heat pump system.However,
Since air-conditioning system and the energy efficiency of heat pump system are improved by better and newer design over time, institute
Amount to be input to the available waste heat of HRU is correspondingly reduced.Therefore, performances and economy of the HRU in terms of its desired use
Decline in benefits.
The alternative for reducing the amount for the conventional energy for being used for heating water source is to use solar energy system.This solar energy
System attempts to directly heat water by passing water through the heat exchanger being connected to solar collector or solar panel, without
It is the waste heat collected by air-conditioning system or heat pump system generation.However, it is this directly heat method need to send on water pump it is relatively long
Distance.Solar panel is typically mounted on roof, and water source is located in building structure (for boiler) or on the ground
(for swimming pool).Heat transmission is completed with multiple collectors or panel further, since needing to pump, is expensive in this way
's.
Many inventors attempt the design higher system of efficiency to heat water.For example, the 4th, 242, No. 873 U.S. of Hino
Patent, which is disclosed, to be heated the gas from heat pump refrigerating loop using radiation energy and the gas of heating is then delivered to storage liquid
The system of device.However, liquid pumping to be heated must be passed through heat exchanger by Hino.The 2010/0114384th of Maxwell
Number U.S. Patent Application Publication heat pump controller, in the heat pump controller, heat pump HVAC fluids enter major loop and wear
Solar heat-collection plate is crossed to provide the energy for being transmitted to swimming pool or domestic hot water.Make fluid circulation similar to Hino, Maxwell
Pass through single heat exchanger.Finally, the complicated heat-transfer system of the 5th, 054, No. 542 U.S. Patent Publication of Young etc., this is
The heat that system obtains during being incorporated in Air-conditioning Cycle from (or from environment panel) in building comes heat hot water case, swimming pool or sky
Between heater.Compressor makes heat medium overheat, and the heat medium overheated is directed to the spiral winding that water passes through.
Young does not utilize solar panel, and is not streamed to the exhaust gas of heating and to be connected in a conventional manner with boiler
Or the heat recovery units (HRU) being connected to the circulation loop of swimming pool.
