The invention discloses a constant-pressure multiple-effect evaporation condensation sea water desalination device with an air medium, which mainly comprises a low-and-medium temperature heat source (13), a first-stage heating evaporator (14), an evaporation condenser (4) and a last-stage condenser (8). The first-stage heating evaporator (14), the evaporation condenser (4) and the last-stage condenser (8) are installed in sequence closely, and the low-and-medium heat source (13) and the first-stage heating evaporator (14) are connected together. The first-stage heating evaporator (14), the evaporation condenser (4) and the last-stage condenser are all formed by combining a plurality of heat exchange plates which are arranged from left to right in sequence, and a gap is reserved between every two adjacent heat exchanging plates to form a flow channel for heat exchange fluid. By adopting the plate-type heat exchange principle, the sea water desalination device realizes multiple-effect air humidification and dehumidification evaporation and condensation for sea water desalination under constant pressure. Heat and moisture transfer is performed between sprayed sea water and overflowing air, and the condensation latent heat of fore effect heat and moisture air can be absorbed at the same time, and therefore, energy recovery is realized and the fore effect heat and moisture air can be condensed to obtain fresh water.

The invention provides a liquid crystal display. Support columns are positioned in opposite light-proof regions of a color film substrate and an array substrate; after a part of light of a backlight source penetrates through a gap between a scanning line and a data line, the support columns shield the light deflecting to an opening area. The liquid crystal display provided by the invention aims at realizing the purpose of shielding the light leaking askant through the support columns shaped as water-retaining walls, so that the width of a black matrix on the color film substrate can be appropriately reduced, and thus the light-proof region formed by the black matrix is narrowed, the area of a color-layer light-pervious region on the color film substrate is increased and the opening rate of the color film substrate and the penetration rate of a liquid crystal display panel are increased. The liquid crystal display accords with the development trends of high brightness, high contrast and high efficiency rate of the liquid crystal display.

A single-phase fluid (SPF) storage is introduced for desalination of high-salt water using thermal energy from a concentrated solar power (CSP) unit. The SPF having a specific volumetric enthalpy higher than that of water at critical point in the operating ranges from 20 to 300 bar in pressure and 190 to 400 C in temperature is used as a new type of thermal energy storage (TES) medium and heat transfer fluid (HTF). It produces wet steam of a quality required by the desalination unit generating both steam for utilization of latent heat and condensate for sensible heat when its pressure is reduced to lower operating pressures. With a MED-TVC unit by using the steam as motive steam, the capacity of the CSP unit and SPF storage can be reduced as much as the energy recycled in the desalination unit.

A method for making high-efficiency air-conditioning and heat pump controllers belongs to the energy-saving field. The automatic control function of the air-conditioning and heat pumps is set by the controller for controlling the ambient temperature, but the current control method does not control the factors of high efficiency and energy saving. And the present invention is: the temperature of the external environment liquid or gas of setting evaporator is t1, the temperature of the internal environment gas-liquid mixture of evaporator is T1, the temperature of gas-liquid mixture in the condenser is T2, the external environment liquid of condenser or The temperature of the gas is t2, then when the temperature of t1 is higher than the set temperature upper limit or the temperature of t2 is lower than the set lower limit and the value of t1-T1 or T2-t2 is less than 15° or less than 10° or less than 5° or When it is less than 2°, turn on the power of the compressor to start working through the controller, otherwise stop the compressor. This method can increase the efficiency ratio to more than 6 by increasing the heat exchange area of ​​the heat exchanger, increasing the heat transfer coefficient k of the heat exchanger, increasing the heat exchange time, and reducing the power of the compressor. The ratio can be increased to more than 50. The controller is an effective guarantee to realize the energy-saving operation of the compressor.
