TL;DR: In this article, the authors proposed a utility model for a refrigerating device for recovering liquefied natural gas cold energy for a cold storage, which belongs to the technical field of energy conservation and refrigerating engineering.
Abstract: The utility model relates to a refrigerating device for recovering liquefied natural gas cold energy for a cold storage, which belongs to the technical field of energy conservation and refrigerating engineering. The refrigerating device comprises a storage tank, a liquefied natural gas pump, a refrigerant pump, a heat exchanger, a heater, an evaporator and a fan, wherein a liquefied natural gas storage tank is connected with a tube pass inlet of the heat exchanger through the liquefied natural gas pump, and a tube pass outlet of the heat exchanger is connected with a user tube network through a gas heater; a shell pass outlet of the heat exchanger is connected with an outlet of the evaporator arranged in the cold storage through the refrigerant pump, and the outlet of the evaporator is connected with a shell pass inlet of the heat exchanger; an axial flow fan is arranged beside the evaporator, and R410A refrigerant is inserted into the shell passes of the evaporator and the heat exchanger. The utility model makes full use of liquefied natural gas cold energy and has a simplified cold storage refrigerating process, so a lot of initial investment and operating cost of the cold storage are saved.

TL;DR: The utility model provided a heat preservation formula gas heater of belt length naked light, including drain pan, combustor, heat exchanger, fan portion dress, gas proportional valve, fuel switch valve, rivers sensor, temperature controller, hot water go out water temperature sensor, cold water inlet tube and hot water outlet pipe as discussed by the authors.
Abstract: The utility model provides a heat preservation formula gas heater of belt length naked light, includes that drain pan, combustor, heat exchanger, fan portion dress, gas proportional valve, fuel switch valve, rivers sensor, temperature controller, hot water go out water temperature sensor, cold water inlet tube and hot water outlet pipe, the fuel switch valve is provided with a little gas outlet with the communicating position of gas proportional valve, still include ever -burning flame air duct, ever -burning flame solenoid valve, ever -burning flame combustion tube and ever -burning flame sensing pin, the ever -burning flame solenoid valve is fixed combustion chamber wall is last, on the fixed combustion chamber wall of ever -burning flame combustion tube and ever -burning flame sensing pin to stretch into in the combustion chamber, the switch -on is connected with little gas outlet and ever -burning flame solenoid valve to the ever -burning flame air duct. Because adopt such structure, behind the combustor stop work, the ever -burning flame can also be fixed time by heat recuperator disposed no. 1, prevents that the temperature temperature difference change of heat exchanger is too big, reaches the comfortable effect of bathing.

TL;DR: A gas heater has a base 16 to support it on a surface such as a table-top 33 and a screw passes through a hole in the top of the table and into the base 16, to secure the heater 10 to the table 33 so that it cannot be knocked over as mentioned in this paper.
Abstract: A gas heater 10 has a base 16, to support it on a surface such as a table-top 33. Preferably, a screw passes through a hole in the top of the table 33 and into the base 16 to secure the heater 10 to the table 33 so that it cannot be knocked over. Fuel is piped to a burner 11, through the base 16 from a source 36 such as a pressurised propane or butane canister. Preferably, the fuel is located below the table and is transmitted to the burner through the screw which is preferably hollow. A parabolic reflector 14 may direct heat and light in a downwards direction. A cover 13 such as a grill may protect the user. Preferably, a control knob 21 operates to control the size of the flame and also functions as a piezo-electric lighter. Although a gas heater is disclosed, the invention may also relate to electric heating.
