Description
Technical field
The present invention relates to the energy utilization technology field, relate in particular to the low excessively method of gas-fired heat pump engine lubrication oil temperature that prevents.
Background technique
As the power source that is located at the compressor in the refrigerant circuit on the air-conditioning, developed at present and utilized gas engine to replace motor.Utilize the aircondition of this gas engine to be commonly referred to as gas heat pump type air conditioner (GHP), the aircondition that utilizes heat pump to carry out operation of air conditioner comprises the refrigerant circuit of parts such as indoor heat converter, compressor, outdoor heat converter, throttle mechanism.Carry out air cooling and air heating is in the refrigerant cycle process to indoor, heat exchange realizes to carrying out between indoor air and the outdoor air to utilize indoor heat converter.See also shown in Figure 1, Fig. 1 is original fuel reserve tank schematic representation, it has fuel reserve tank 1, in the fuel reserve tank 1 is shoe cream room 2, be respectively equipped with return opening 3 and the oil outlet 5 that communicates with shoe cream room 2 in the above and below of fuel reserve tank 1 sidewall, on fuel reserve tank 1 sidewall between return opening 3 and the oil outlet 5, be provided with oil temperature sensor 4, in shoe cream room 2, also be provided with electric heater 6.
The aircondition that utilizes heat pump to carry out operation of air conditioner can utilize less expensive town gas to act as a fuel, so compare with the aircondition of being made up of the compressor that utilizes motor (EHP), operating cost reduces, and can reduce the demand to electric power.
Gas-fired heat pump can reclaim engine waste heat, improves heating capacity greatly, uses at cold area to have excellent economy.But, stop using gas-fired heat pump at cold area, the lubricant oil of motor cools down gradually, and it is big that viscosity becomes, even solidify, and influences the motor next time of startup once, adopts electric heating to keep lubricating oil temperature usually, and it is more to consume electric power.
Summary of the invention
The object of the present invention is to provide a kind of parts that can prevent that the engine lubrication oil temperature is low excessively.
For realizing above purpose, the present invention has taked following technological scheme: gas-fired heat pump lubricant oil thermal insulation apparatus, include fuel reserve tank, shoe cream room, in shoe cream room, be provided with electric heater, the above and below of fuel reserve tank sidewall is respectively equipped with return opening and the oil outlet that communicates with shoe cream room, is provided with oil temperature sensor on the fuel reserve tank sidewall between return opening and the oil outlet, is provided with thermal insulating material between described fuel reserve tank shell and shoe cream room shell; Be provided with dividing plate in the shoe cream room, described dividing plate is arranged on the below of electric heater, oil outlet, and it will be divided into two-part in the shoe cream room, and top is divided into shoe cream room, the bottom is divided into accumulation of heat liquid storage chamber, is provided with accumulation of heat liquid and fills mouth on the fuel reserve tank sidewall of described accumulation of heat liquid storage chamber.
The principle of the invention is: lubricating oil tank fills heat-accumulating material, and lubricating oil temperature is kept in the heat-accumulating material heat release when lubricating oil temperature reduces.
Modular construction of the present invention and working principle comprise as follows:
(1) the lubricating oil tank outer surface is incubated processing, reduces the external heat dissipating capacity of lubricant oil;
(2) cavity of isolating with lubricant oil is arranged at the bottom, fills heat-accumulating material in the cavity.
(3) emit the latent heat that stores by heat-accumulating material and keep lubricating oil temperature.The phase transition temperature of heat-accumulating material is slightly higher than the minimum operating temperature that lubricant oil allows.If when lubricating oil temperature was lower than heat-accumulating material temperature, heat-accumulating material was heat transferred lubricant oil, lubricant oil and heat-accumulating material temperature slowly lower; When the heat-accumulating material temperature arrives its phase transition temperature, heat-accumulating material begins constant temperature phase transformation heat release, and lubricant oil is kept stationary temperature, and heat-accumulating material is progressively changed into solid-state by liquid state; When the accumulation of heat material all change into solid-state after, lubricant oil and heat-accumulating material temperature progressively reduce, lubricant oil is lower than minimum operating temperature.If when lubricating oil temperature was higher than heat-accumulating material temperature, lubricant oil was the heat transferred heat-accumulating material; When heat-accumulating material partly or entirely is that solid-state, solid-state heat-accumulating material melts heat absorption (accumulation of heat), heat-accumulating material is temperature-resistant; When heat-accumulating material was liquid state, heat-accumulating material is elevated temperature progressively.
(4) sensor of installation and measuring lubricating oil temperature in the lubricating oil tank.
(5) electric heating tube is installed in the lubricating oil tank.Long when dead time, heat-accumulating material all is converted into solid-state, and lubricant oil is lower than minimum operating temperature, starts electric heating and keeps lubricating oil temperature.
The present invention compared with prior art has following advantage:
(1) keeps lubricating oil temperature with electric heating hardly, reduce power consumption
(2) still can keep lubricating oil temperature behind unexpected the power failure, determine normally to start immediately behind the incoming call.
