The application provides a kitchen system, which uses exhaust gas of a power equipment to heat a clean water source combined by condensate water of an air conditioning system and hot condensate water of a steam heating equipment, turns waste into treasure, generates heat energy, heats drinking water, rice or dishes, is healthier for human body, protects cabin environment of the kitchen, and the secondary use of the hot water source can also clean and extinguish the exhaust gas and drainage system of the kitchen, and can also heat the condensate pipe of the air cooler in the food freezer and the pipe system in the low-temperature environment such as the air cabin of the two outer wings or the open deck, so that the pipe system does not freeze. The kitchen system circulates and uses the exhaust gas of the power equipment, the condensate water of the air conditioning system and the hot condensate water of the steam heating equipment, thereby reducing the electric load of the ship, conforming to the green and low-carbon development trend of the ship industry, and effectively overcoming the shortcomings in the prior art and having high industrial utilization value.

The application discloses a high-temperature shale gas long horizontal well drilling temperature control system and method, and belongs to the technical field of drilling engineering. The system comprises a drilling tool assembly, a ground cooling device, a top drive, a mud pump, a solid control device and the like. The drilling tool assembly comprises a rotary steering tool, a screw motor and a drill pipe. Meanwhile, the application also discloses a high-temperature shale gas long horizontal well drilling temperature control method. The application adopts theoretical analysis and fitting methods combined with field test data to simulate the bottom hole circulating temperature of the drilling fluid. By adjusting the drilling fluid density, the mud pump displacement, the drilling tool assembly and the number of revolutions of the drilling tool assembly, the application simulates and observes the influence of different parameters on the bottom hole circulating temperature of the drilling fluid, thereby providing a reference basis for optimizing the field construction parameters of deep high-temperature drilling.

The application discloses a building load control method based on phase change energy storage, wherein at least part of rooms in the building are air-conditioned rooms, and a cold storage structure is arranged on the top of the air-conditioned room; the control method comprises the following steps: determining indoor temperature according to real-time electricity price and building load; when the real-time electricity price is in a first period, controlling the air conditioner to provide cold energy for the air-conditioned room according to the indoor temperature and controlling the air conditioner to provide cold energy for the cold storage structure based on the indoor temperature; and when the real-time electricity price is in a second period, controlling the air conditioner and the cold storage structure to synchronously provide cold energy for the air-conditioned room based on the indoor temperature. By adopting the cold storage structure and the air conditioner synchronous instruction, the use of valley electricity and flat electricity is increased, and the use of peak electricity and peak electricity is reduced, so that the building electricity cost is reduced, the building power load in the period of peak electricity and the period of peak electricity is reduced, the peak load is filled with valley electricity, and the summer electricity pressure is relieved.

This invention relates to the field of hot water supply equipment technology, and more particularly to a hot water supply system with grid peak-shaving function. It includes a water tank, a liquid storage shell fixedly connected to the water tank, a third pipe connecting the liquid storage shell, a first fixed shell fixedly connected to the water tank, an electric heating rod fixedly connected to the first fixed shell, a rotating ring rotatably mounted on the first fixed shell, a second fixed shell rotatably mounted on the rotating ring, a second circulation pump mounted on a connecting plate of the water tank, a fourth pipe connecting the liquid storage shell and the second circulation pump, a fifth pipe connecting the second fixed shell and the second circulation pump, and a sixth pipe connecting the first fixed shell and the liquid storage shell. This invention uses the liquid storage shell as a transfer storage chamber to prevent the hot water temperature in the water tank from dropping, while the electric heating rod heats water and stores it in the water tank during off-peak electricity usage periods, reducing the electricity load during peak water usage periods.
